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)
OK, but then please make one line here until then.

This will be done after new Meteor rendering engine. They have some new stuff about attributes.
