Renamed EntryReader class to EntriesPagination.
FeedsController.index now accepts an optional "page" GET parameter.

If received, the subscribed feeds are paginated (25 feeds per page) and the requested results page is returned. Otherwise, all subscribed feeds are returned like before.

Not yet implemented: make use of this pagination from the AngularJS client.
AngularJS client retrieves feeds from the server in a paginated fashion.
