Removed a few debug messages from mapchooser

Fixed amb1957 - Mapchooser now counts arena rounds correctly.
Fixed amb1925 - Mapchooser countly rounds incorrectly during an RTV
Fixed amb1920 - Cleared retry timer
Fixed amb1921 - Cancelling a vote now marks the vote as complete

Fixed build.

"Nice" improvement DS.

Improved bot detection slightly. This was meant to go along with the fix for amb1801.

Reverted to old cmd functionality for original engine.

Fixed bug 1750 and bug 1801. Orange Box changes the command processing heuristics without telling anyone, it looks like executing commands during the command buffer processing causes insertion to the beginning of the stream rather than end. Moving our callbacks to occur in a new frame seems to alleviate this.

Fixed crash when TF2 extension couldn't load.

Fixed bogus warning from GCC.

Add a poor man's build trigger.

Fixed OP_SWITCH accidentally using the wrong address to get the pcode base (regression based on assumption of JitWriter::inbase).

Ew! No spaces in filenames.

Fixed amb1928 (EndOfMapVoteEnabled should be optional).

Fixed build for new jit. Can't seem to kill off one of Microsoft's retarded NONSTDC warning, oh well.

Removed debug mode from plugin_settings.cfg.

Landed sourcepawn-1.2. The big changes:

1) JIT compilation/optimization now occurs per-function, and only when functions are first used. We're now officially a whole-method JIT rather than an AOT compiler (albiet, still a simple JIT). This has two implications: Functions are now much better abstracted internally, and loading a plugin is now much less expensive. If a function contains calls to other functions, THOSE functions are only compiled when they're invoked as well.

2) I've removed debug mode. We always show full backtraces now, as there was a very cheap way to implement this which really cleaned up everything. This is great for a number of reasons -- there's less code, the JIT is better designed, we don't need to relocate debug tables, and best of all we no longer have to tell users to enable debug mode at their own expense.

Fixed amb1924 - Nextmap command now checks if end of map voting is enabled

Initial Import of beta structs extension.

amb1919 - HasEndOfMapVote finished should be separate from determining if the vote will run at all.
amb1915 - Mapchooser should disable round end changes if forced to change early.
amb1901 - Timer errors with mapchooser

Fixed amb1899 - Duplicate maps in auto generated maplists

Fixed amb1918 - Ban menu should compare userids, not client indexes

Increased Clientprefs error reporting and a rare leak on database connection failed.

Fixed a few file handle leaks

Fixed amb1891 : Basechat didn't check for blank message in private say's

Added custom gamedata section parsing to GameConfigs.

More file handle leaks fixed.

Pending Map should no longer be shown when mapvotes are disabled.
Removed tf2 include from mapchooser.
Moved sm_setnextmap to mapchooser and made it block the end of map vote.

fixed amb1885: regression in IsInExec() which caused ThrowNativeError to fail

Probably helps to close files after opening them.

Nextmap command (basetriggers.sp) will now show 'Pending Vote' if mapchooser is running, and the vote has not yet occured.
Few cvar description changes in rockthevote.sp

Fixed a bug where natives with no owner could be bound (crashing).
Fixed a bug where FakeNative entries were leaked.
