Jean-Philippe Lang 1c44600c62 Added per user custom queries.
Any logged in user can now save queries (they are not visible to the other users).
Only users with explicit permission can manage queries that are visible to anyone.
The queries list is removed from the "Reports" view. It can now be accessed from the issues list.
