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)
I don't see any other way than authorName. Meteor doesn't support any other sorters than asc/desc by document fields. I didn't feel it was such a big deal if people come first, then groups, but I guess it doesn't hurt to add authorName.
