Additonal stuff: Fixed + refactored help command. Removed 'Usage: ' from all commands. Created 'player.hasPermission(permission)' function. Created default for Usage annotation. Created hashmap version of 'getHandlers' and renamed the original to getHandlersAsList()
Added player "Help" command, added server "sendmsg" command, changed getAcccountByPlayerID to public in DatabaseHelper, and allowed player commands to be submitted with "/" and "!"
