Fixed a few movement flag related issues.
WG no longer prefixes greeting/farewell flags with '**', allowing people to customize the message.
(Adding &c** to the beginning of the message will give previous behavior)
Removed the "game mode locked" message since it returns false gamemodes when being called inside a player move event.
Use getName instead of toString for displaying world name.
Large patch with lots of changes and fixes.
- Unified movement checking. Teleporting is now handled by
  entry/exit flags. Additionally, a region movement event is
  much closer to being added.
- Fixed an issue with enderpearls and exit/entry flags conflicting.
- Fixed a null check issue in several commands.
- Fixed allowed and blocked command flags making false matches and
  improved support for blocking/allowing specific command args.
