added preliminary FTE_SQL code (not in a usable state), current problems: WINDOWS ONLY, database connect is hardcoded to a local server, conditional wait needed for worker thread (currently consumes 100% cpu), query requests and results should be a queue not a stack, sql init and deinit is in the wrong place, project and defines need updating, tons more things git-svn-id: https://svn.code.sf.net/p/fteqw/code/trunk@2941 fc73d0e0-1445-4013-8a0c-d673dee63da5
