1. Fixed the redundance problem between bug_actiongroup.php and view_all_bug_update.php ; the code of bug_actiongroup is reported on the latter, and the page deleted.
2. Bugs which are mass-treated now have a new handler only when assigned or "status-updated".
3. Fixed the number of the current page and put it at the right column on view_all_inc.php
