First pass at Kickass Engine

Parse and return results correctly. Pages numbers taken care of.

Not done, and maybe to do :
- 'content' : I don't know what it could be. Maybe votes ?
- 'categories' : the results are not filtered by categories, because I don't see how to do it properly : there are too much categories on Kickass. Is 'video' only movies, or also tv show or porn ? So for now, the category is 'all'.
- Favicon/icon : may be a good idea.
Add KickAss engine
Add icons and badge for the themes
Add kickass in engine list
Add content for the result from kickass
