Fixes heal flag bugs when player.maxHealth > 20

With the new Bukkit Changes the Player Health can be above 20, this fixes the magic number by using the now built in Bukkit functionality.

Examples of this bug were Health jumping to 1/20 hearts when having a heal-amount: -1
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.
Merge remote-tracking branch 'upstream/master' into sakura
