Merge lp://staging/~stolowski/unity/expand-2nd-home-category into lp://staging/unity

Do we really need to hardcode it? A category cannot expand itself using libunity etc.?

Unfortunately there is no way to do this from lenses. Ideally, we should have a new expand-in-home-on-empty-search lens property in libunity Lens class, that would be passed via existing as{v} hints over DBus. I discussed this with Neil and he suggested handling it as an edge case on unity side only, as it's sanest for 12.10.

Can we at least do this when the search actually finishes and not arbitrarily after adding a few results?

Otherwise the category might get expanded, but as another lens finishes search and pushes more results it will again get unexpanded... Or is that what what we actually want?

> lens_->view_type == ViewType::LENS_VIEW

That doesn't look right, we should be using HOME_VIEW in home lens (if that's not the case the id check should suffice)

Got it.
