As of this commit, LORD2 keeps track of the last time a key was
pressed, and a timeout occurs five minutes after that if it's
waiting for a key.  This has issues as the getstr() timeout does
not behave in this manner.

However, if the timeout callback style works, getstr() and the other
dk functions can grow callback support pretty easily, and this seems
like it may be the best way forward.

Further, disconnect handling should be tied up in this, and dorkit
does not have very robust features for this.  In most cases, a
disconnect will be treated the same as a timeout, so the same solution
should likely be usable by both.

The biggest challenge is preventing the need for all the code to
have exceptional condition handling, which can be quite tricky as
battles can end by running a REF file (For example, the training
centre).  This would mean all code paths reachable via REF calls
would need to fail nicely in the face of a connection loss/timeout.

There were 2 bug identified by issue #230:
- the "Fwd:" prefix being added to the message subject was being treated as a filename. I first thought to just remove this subject tag, but then thought it best to just ignore obviously invalid filenames in the subject in the first place.

- when forwarding files to a netmail address, the 'to' extension (user number) is 0, so the file will be in the data/file/####.out directory of the sender instead.

We have 4 places (at least) where the message subjects are parsed and only one of those places currently supports quoted filenames (e.g. with spaces in them) and some of the others (e.g. QWK) don't support multiple filenames at all. That should be fixed.

Renamed from *.asc to *.msg
Replaced mouse hot-spot @-codes with the color-coded hotspots
Removed trailling newline in head.* to avoid line-wrap in PabloDraw
on @ include line
The Sysop Menu line still wraps (in PD) - no easy solution for that
just yet.

For nickshanks1 in IRC.

While we're looking at the exit behaviour, use the recfile close
method now instead of f.file.close().

About the only thing still missing is the ALLOFF utility which is
simple enough, but various other bits really need to be fixed before
that is done.

A couple minor TODOs (can't launch REF editor for example)

Also, keep the cursor at the player position a bit better.

Too lazy to add everything, but I need these for l2cfg.

The various __GNUC__ macros are defined in other compilers and
indicate support for a C language standard and can't be used to
detect if gcc the compiler is being used.

Beginnings of the map editor created, common functions from lord2.js
moved into l2lib.js for sharing.

Apparently, I've never needed this before.

Fixes moveback/update duplicate character issue in REFs.

In various places (most visibly stoneb.txt pawn shop), the following
is used:

@if <condition> then do begin
 @begin

The begin on the @if line must be ignored, and the @begin on the
second line starts the block.

instead of the RFC977 502. Reportedly, this will trigger Thunderbird to prompt
for or send client credentials. This should fix issue #208.

The service clients count is now a protected int, so deal. On Windows, this was resulting in the "total" and "served" values logged as 4294967295.

from Tracker1: agree -auto should probably be removed

- When a player number is passed in an IF, subtract one to get the index
- Normalize @begin handling for all @if lines.

This is a full-screen game, so don't let this ctrl-key handlers mess up the
game/map display.

pass true if blink is desireable for blink/high-blink fonts.

Previously, if a blink or high-blink font was specified in a font section
it was assumed that you did not want the terminal to actually blink the glyphs
displayed with that/those fonts. In some cases, blink may be preferable, so
if wantblink=true, then leave blink enabled on the terminal for blink/
high-blink fonts.

- saybar needs to leave cursor at 78,20 for BETTER.REF and
  TALQUIZ.REF
- buymanager and sellmanager start on the current line, not a
  hard-coded one
- buymanager and sellmanager need to clean their area on return
- handle do handlers in if before checking for begin (assuming do).
  Fixes issue in GIVE.REF where "then goto begin" was interpreted
  as "then do begin".
- "Fix" more prompt in @key to not center and always display
  "  <MORE>" as the prompt.  A number of things use @key after @saybar

Much better than the default "SyncConsole".

- Trim bar to 76 characters (triggered by MORTAL.REF)
- If the player initial map can't be loaded, move to 0,0,0
- draw_map() can't auto-load the players map
  (ORACLE2.REF loads a map without the player on it)
- When we draw a new map, set last_draw to undefined
- If you move off the edge of a map into an undefined map, simply
  don't move (triggered by GLENDALE.REF)
- Move play on map *after* a REF is ran
  (and you're potentially moved back)

Not sure why it was removed, apparently by accident.

Fixes the new issue where you would see the player move when x and y
are changed, but should still leave the smackrod happy.

Fixes CNW "Vehicles & People" some more.

Fixes CNW "Vehicles & People" people list.

This provides a way to create muscle memory for random fights...
HOME will always take you to 'Attack' and END will always take you
to 'Run Away' now.

Two birds with one stone, yay!

Previously, it did a case sensitive match against names that started
with what you typed including LORD codes.

Now it strips codes from both and does a case-insentive substring
match.
