UI python code

Fixed current tests to use os specific separator, added some code for xmlrpc server for testing
Added descriptive variable/object names
Moved classes into separate files for easier importing in different modules, updated UI code - still not functional.
Disabled some elements that shouldn't be enabled on start, changed object names
Implemented folder add button actions, added sub_model that'll be used later for subtitles
Added 2 tabs, one for settings one for searching and downloading.
Wider main window
