Fixes recently-introduced crash when generating text drop files (e.g. XTRN.DAT, SFDOORS.DAT, DOOR.SYS, CHAIN.TXT) on Win32 (only) where a 'long int' is still just 32-bit.

Fixes CID 351271

Might add some other statistic for these relayed posts at some point.

Hunting down and destroying some super old SBBS code now. :-)

Defines the field indexes for records in csts.ini

Generates a "Dd Hh Mm" string from a specified number of minutes.

DDLightbarMenu OnItemNav on initial display

See merge request !168

DDLightbarMenu can now optionally call its OnItemNav function when
it's first displayed.  By default this behavior is disabled, but it
can be enabled by setting the (new) callOnItemNavOnStartup property
to true.

I was stripping the path here... oops.

*/dsts.dab was replaced by dsts.ini.
*/dsts.ini is just a text file, you don't need a special editor.

*/dsts.dab (daily statistics and running totals) -> */dsts.ini
*/csts.dab (cumulative statistics / log) -> */csts.tab

* dsts.ini now has both daily and total stats for all fields (not just timeon and logons).
* dsts.ini is now an easily modifiable text file - no longer need dstsedit (here-by deprecated and soon to be deleted)
* dsts.ini and csts.tab support 64-bit upload/download byte stats and are very extensible for future fields to be added or extended > 32-bit (this was the main inspiration for this overhaul, but it was overdue and already designed for v4, pretty much)
* csts.tab is a tab-delimited fixed length record format suitable for easy import to a spreadsheet program or parsing with scripts. Each day is a 128-character LF-delimited record with tab-delimited fields of plain ASCII text.
* All fields except timeon in dsts.ini files are updated immediately and by more non-terminal servers (e.g. post statistics from web UI scripts).
* New user stats are tracked more than just for "today".

The upgrade of these files is automatic and built-into SBBS.

Still to do: overhaul the slog utility to support the new csts.tab file format.

Windows doesn't allow multiple directories of the same name only differing in case, so don't on *nix either.

Supports mixed Ctrl-A and ANSI messages.

ANSIs of any length should display correctly.

ANSIs wider than 79 columns will be truncated (not horizontally scrollable).

Animated ANSIs will not render with their animation sequences in tact. :-(

Create expand_ctrl_a() method that expands Ctrl-A attribute codes in a string
into ANSI escape sequences.

If set to true, when setting the ANSI property, rather than throwing away
vertically "scrolled" lines, just keep extending the height to accommodate the
new required vertical size (height).

yes/no prompts can be disabled by just setting a string to a blank string.
Disable these prompts by default (you can reeanble in your own text.dat if you
want).

Fix the fix to issue #380.

Thanks for letting me know Keyop.

Fixes crash reported in #381.

And data/dirs/*.msg display file. Now you can have any supported menu file in this location if you wish.

I'm so tired of this 30 year old frequently asked question.

If a sysop really wants their Synchronet BBS to only work correctly for ANSI users, I suppose that should be their prerogative.

I always felt that by not detecting/displaying menu files when the minimum set of files was not present, I was helping sysops to identify an issue with their system (which would not work correctly for non-ANSI users). *And* I always felt that having a single menu/display file that correctly supported both ANSI and non-ANSI users was a nice convenience (who really wants to maintain multiple versions of their menu files?). But I'm so tired of answering this question, I just give up.

Hopefully this doesn't break anything for anyone. <shrug>

That previous commit made all *.40col.msg files display for 80 column users. Not my intention.

So revert to the previous behavior of *.XXcol.* display files. I didn't want to go renaming a bunch of menu files as a result of the previous commit and I didn't want a bunch of sysops with *.XXcol.* files to be suddenly surprised at their new BBS behavior.

And introduce a new file naming convention, *.cXX.* (where XX is a MINIMUM column width). This is the same naming convention used by Mystic, which also treats it is as a minimum terminal width, not a required exact width.

DDMsgReader: Now calls bbs.edit_msg() to edit an existing message.

See merge request !167

e.g. display basename.132col.msg even if the terminal is 133+ columns wide.

Fixes issue #380.

glob() is case-insensitive on Windows already, so create a work-alike for *nix.

Fix for one of the problems described in issue #380.

bbs.menu("random*"); would display column-width-specific files (e.g.
random.132col.msg) even when they weren't appropriate for the current
user terminal width.

This is fixed by truncating the filenames matching the requested pattern at
their first-dot rather than the last.

The downside is, you can't have a set of random.#.* files, where # is the
unique part of the filename and * is the file-type extension. Just use
the naming pattern "random-#.*" instead (or something similar) instead.

Fixes recently broken Win32 build

I knew I created these is_valid_*num() functions for a reason!
