0.5.1

Changes since 0.5.0:

• Deprecate team/match text descriptions in match configs, they may still be used, but in a multimap series the mp_teamscore_* cvars will be set and are generally more useful than manually setting match texts.
• Bug fixes around pausing
• Added get5_game_state cvar, this is intended for other plugins to be able to query game state without requiring a hard get5 dependency
