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)
It comes from the fact that tooltips (like dropdowns) are styled in the controls.styl file, so I have also all code in lib/controls. Maybe one day when controls becomes too bloated and needs to be divided it can be separated out.
