refact search providers into separate plugin - issue #152
Optimized search for album with a given ext_db_key to only try to match against an album with the corresponding name.
Fixed some stuff on the "Cover" tab of the bottom pane:

* Fixed the hiding of the show more results links. Now it hides when it haves to.
* Floated the Google branding div to the right. This way the show more link is more visible and easily accesible, while the branding is still there but doesn't obstruct the rest of the interface.
latest translations - also translates separate search providers plugin
Adapted some syntax to PEP8
Modified the ListWindow and the OptionsListViewWidget to recreate the liststore only when necesary (issue #123).

* Removed the activate method from the ListWindow and moved the relevant code to other places to help with the flow of the OptionsWidget.
* Correctly implemented the update_options and update_current_key callbacks to do what they should (recreate the list and select the currently selected item respectively)
* TODO: maybe the ListWindow should be merged with OptionListViewWidget? Right now they seem like two layers of the same thing, maybe it could be simplified by merging.
* TODO: the "mouse" flag for the window position seems to put the center of the windo on the mouse, instead of the corner (like the poups). Should look into that.
Fixed the issue when the genre ListWindow would get destroyed after pressing [ESC] (issue #123).
