Completely removed support for old style Lua plugins (can use both Plugin and NewPlugin in settings.ini for now)

Removed cPlugin_Lua, obviously
cPluginManager stores plugins by their (folder)name
cPluginManager now scans the Plugins folder for potential plugins and adds them as non-loaded plugins
Added a DisablePlugin and LoadPlugin to disable and load plugins on a per-plugin basis instead of all at once
cPluginManager::FindPlugins refreshes the plugin list by removing non-existing plugins and adding new plugins
Made it incredibly easy to use new plugins from the WebAdmin
Exposed some food/hunger related functions in cPlayer to Lua
