search: return the number of a certain attribute

[GoogleCodeExporter]

See https://camlistore-review.googlesource.com/#/c/3688/1 for context.

We eventually want to change describe so that it doesn't return every single 
attribute of a permanode, because doing so can be very inefficient (see bug 
435).

However, once that it done, it would be nice if describe could allow clients to 
get the number of a particular attribute, attribute pattern, or at least 
specifically whether there are any 'children' (camliMember or camliPath:*) 
attributes for a permanode.

The UI would like to know when laying out a search result whether a permanode 
has any children so that it can quickly switch to the correct detail aspect(s) 
on click. Without this, we either see stutter in the UI when switching, or have 
to block layout of the detail view on a search query.
