Added the serialize module.

lists and dicts.
added RPC functionallity.
Frontpage overhaul
The frontpage of the website was completely redone. The main focus was using AJAX to improve load times. Some providers (like the piratebay provider) can takeup to a few seconds to load so AJAX is being used to run these long requests in the background.
Renamed some packages and modules.
The root package 'popcornlime' has been changed to 'plime'.
All provider modules have been placed inside a provider package.
Merged transmission_rpc module into the transmission module.
