Separate names with a comma.
Control the gamemode in different worlds.
Only one change: /pwgm exclude save to the config properly now.
Fixed spelling mistake which caused nothing to work.
Tested things, they should all work now...
Fixed bug #1: Usernames shouldn't be case-sensitive.
Fixed bug #2: Adding a world without giving a name causes a server crash.
Added /pwgm include <player> (Opposite of /pwgm exclude).
Rewrote config to be easier/ more extensible. (You will need to set up worlds again)
If a world has no gamemode setting, it defaults to the server's default gamemode instead of hanging in limbo.
