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

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

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

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.

- 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.

- 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

- 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)

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.

Also, remove trailing whitespace from labels (see CNW items.ref @default)

- Don't clear the line until you're on column 79 and about to draw
  that last char.
- Clear all rows after the map based on dk.console.rows.
  Clear to end of screen would still be better though.

Call update_update() as well as update() when we receive UPDATE.

Adjust some comments
Use pretty_int() wherever we're displaying a number
Clamp more integers
Don't clear screen before drawing map

Also, alphabetize the handlers.

These now seem work both JS <-> JS and JS <-> L2.EXE.
The only issue seems to be that infinite lives mode with L2.EXE, if
you're killed and come back to life, you are no longer "on line".

This does not seem to be an issue with the JS version for some
reason, and may need to be "fixed"(?)

Mark other player as not busy anymore after hail is done, loop
through the hail menu until you leave, and retain the currently
selected option between hail menu choices.

This also enforces the "no fighting" rule, which doesn't really
need it yet since no fighting actually works currently.

Fixes issue where the "Disguise" item doesn't work as advertised,
making winning as good much more difficult.

update_space() assumed the cursor was at the correct location, but
it never was.  This caused a visual glitch when using the smackrod.

Fixes glitch when giving the guard at the bridge an apple to get to
Castle Coldrake.

If the script called from winning a battle (such as in training)
ended up having a battle (such as leveling multiple times in one
visit), weird bits of map would be displayed.

Define the s&he variable.
prevent replace_vars() -> getvar() infinite loop on undefined var
Move to end of vbar after selection
Lower-case font path

User when not specified is 'SYSOP' not 'Local User'
Use lower-case, not upper-case by default.
Lower case all filenames from scripts.
When a label is defined multiple times, the *first* instance is used.
Labels can have spaces in them.
Allow passing label+file.ref on command-line.
