Add support for Forge mod commands to hook into Bukkit permissions.

When a forge mod registers a command through the CommandHandler, it will
automatically be registered with Bukkit using the CommandModCustom class.
This class is solely used to register the command prefix, permission node,
and allow us to check for valid permissions through Bukkit. The permission
node will be set to the class name of the mod's command class that is
being registered.
Added CraftSimpleCommandMap to hook into dispatch instead of Bukkit.
Added missing ModCustomCommand and changed references. Fixes issue #27

Add configuration options to disable plugin file remapping

In bukkit.yml, you can now control plugin remapping in mcpc.plugin-settings,
either globally or per-plugin (keyed by the plugin's filename, before '.'):

remap-plugin-file: if true, the plugin is run through SrgTools ApplySrg,
creating a plugin file of the same name but prefixed with 'ported_'. If
the plugin does not function as expected, you can disable this option and
try with the original version of the plugin.
