This is a smaller release changing and fixing a handful of things:

- Tweak: Max clients connected is by default 6
- Tweak: Max clients connected is read from the database table "map", specifically the column "player_limit".
- Tweak: General clean-up of warnings and errors in the code, as well as updating the syntax to SM 1.11 (like steamtools.inc)
- Fix: new players will now be added the "player" table in the database.

I'll continue working on issues and features. The next bigger addition will be translations.
