Some little refactoring, made the distro filter work and mockup added
for the architecture filter.

* Renamed ListController::show() to ListController::isDistroVisible()
* Added ListController::add_box() and ListController::add_architecture()
* Replaced the button group for the distro names with simple checkboxes
  because the button group didn't toggle the distros' visibility
Architecture filter implemented & tested
More CentOS boxes added to prototype new filters.
Grouped some attributes & methods in sections in ListController
Implemented the provider filter
Added a (outcommented) template for the size slider and the corresponding model
