admin: Show project quotas

Project quotas are shown in two different places:

a) In the project summary, where they have to be displayed horizontally
and
b) in the details of a project, where they should be shown vertically.

Besides showing the project quotas properly, we must show and the
requested project application resources properly, since we currently
have no direct way to show them.

Therefore, for each project we will show either the latest state of its
quotas or the latest state of its application resources.

admin: Inform about hidden items in details

Display the following stats at the start of each association:

* Number of hidden deleted entries.
  Note: if the administrator has specifically asked to show deleted
  entries, then this number will be zero, even if deleted entries are
  present
* Number of entries shown vs. number of total entries.
  The number of shown entries is always smaller or equal than the limit
  in the settings.

The underlying code for details has been largely revamped to allow
showing the above.
