Each site is now accessible via a tab in the main tabpane.
The tab itself contains the different pages, which are specific
for the site (e.g. online, followed, featured etc.)
This step should enable the application to handle different camsites.
At the moment only chaturbate is available, but others like MFC can
now be added. There might be still some things to do, like the settings
and HttpClient etc. But this is the first step to support more sites
than only Chatubate.
