Add new API function wrappers to traktAPI class.
Added the ability for the plugin to create tags from lists on trakt, as well as from watchlists (if enabled), and from ratings (if enabled, with a minimum value).

Added 5 new actions, addtolist, removefromlist, updatetags, itemlists, and managelists.
RunScript(script.trakt,action=updatetags) will cause xbmc tags to be updated from trakt lists based on settings.
RunScript(script.trakt,action=itemlists) will allow a user to edit the lists a movie/show belongs to within XBMC, and add new lists.
RunScript(script.trakt,action=managelists) will allow a user to edit there trakt.tv lists from within XBMC and add new lists.

RunScript(script.trakt,action=removefromlist,media_type=<movie|show>,dbid=<#>) will allow for adding an item to a specific list, media_type and dbid are optional, if not included, this will apply to the selected item.
Update service thread to handle new actions.
