- Store incomplete search results in session and re-send search requests
to the server if returned before complete (this should avoid hitting request timeouts).
- Display full folder path on mouseover in message list
- Remove pthreads implementation stuff as this wasn't really working
Removed rcube_result_index::intersect() method.
Changed rcube_result_index::filter() to filter in the same way as
rcube_result_thread::filter(), which means it actually does array_intersect().
Added tests scripts for rcube_result_index class.
