Catalogs of entities

Provides views of latest publications, people, annotations, groups etc.

Note: existing views were refactored for more unified code, so the diffs are large in some cases, but insignificant (about, terms, privacy pages etc. due to removal of the unnecessary .simple class)
On the second thought I don't think this is really relevant. By sorting we would promote large collections. Difference is that commenting and annotating is a thing done by others, so in some way "upvoting" through action. Number of publications is something you do yourself. So I would have sorting by annotations count and comments count, but not members count or publications count. (But we should have a display of members count and publications count.)

But I do not have a strong opinion here, so you decide.
