FIXED Perk rewards not executing when a race/class was picked

TWEAK /races reset no longer immediately removes the race/class, instead a player can no longer exit a race/class selection screen until a race/class is selected

Updated plugin to accommodate ValhallaMMO Beta API changes.

ADDED Multiclassing!

FIXED Players getting stuck on race/class selection

FIXED issue where race/class picker could be closed
FIXED issue where certain stats, specifically the ones which apply in pve or pvp, were not applied for the appropriate targets

TWEAK added option to config.yml where you can choose to have the menu open when the player starts moving instead of when they first join. Sometimes this is necessary when you have an authenticator plugin
TWEAK race/class pick confirmation messages now have their race/class display name trimmed before insertion
TWEAK race/class pick icons now have their attributes hidden

- Added reload command
- Fixed StackOverflowError
- Added capability to add a delay before certain commands are executed, just add something like <delay:100> before the command and it'll execute after 100 ticks of delay (which is 5 seconds)

Added 4 new placeholders to display the race and class a player has.
%valhallaraces_racename%
%valhallaraces_raceprefix%
%valhallaraces_classname%
%valhallaraces_classprefix%

The prefixes can for example be used in chat formatting to let other players know which race and class the others are

I forgot to lock the one important command of this plugin behind a permission, so now players can't use them )
