kLocks

Changed en.yml "CROUCH" to "key:key.sneak" which shows the control of the player; Added admin utilities like "/klocks forceunlock" and "/klocks getcode"; Added configuration options for togling Lockable Invulnerability

Fixed some bugs. (%prefix% not replaced in the usage message of /unlock & /changecode usage message not working)

Added new option to use arguments instead of "Chat Input" when entering a code. New syntax: (Things in square brackets "[]" mean optional argument) /lock [code] /unlock [code] /changecode [old code] [] If you type the old code in /changecode, the new code argument will be a requirement!

The First Release of kLocks!
