Add access to CGameRules and its properties (#363)
* Add back game rules * Initial commit Since the Linux build doesn't like running with opaque types, I had to change back a lot... * Moved stringtables stuff to the appropriate files Fixed StringTable.changed_since_tick() calling the wrong C++ function * Added static method ServerClass.find_server_class() * Added back those two * Reimplemented gamerules functions using string tables * Cleanup, sanity checks and typos * Fixed spacing * Cache SendTable
