Added numerous in-game commands to configure general and game-specific settings. This mostly eliminates the need to manually edit the configuration file unless you want to tweak rarely-changed settings or prefer direct editing.

Added confirmation in chat from commands. Previously commands would mostly give no indication when they worked correctly; only providing feedback on errors. Now commands also give confirmation on success.

Bug fixes:

• Fixed a problem with the plugin load order with Multiverse that can cause a problem running Boost in a separate world.
• Fixed a problem from using a default world name of 'world' if none is specified.
• Fixed recognition of world names in mixed case.
