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)
`TypeError: Object.keys called on non-object` error is not critical, I reported it some time ago: https://github.com/meteor/meteor/issues/2070

For stuck processing, hopefully that will be addressed with new version of pdf.js.
