Bug 920246: Adding category filter to admin/groups/groups.php

- Like the group/index.php page with the filter, this page also
has a problem with the button when the width of screen is too small
- Added a parameter to an existing helper function for groupcategory
(build_group_list_html
- Helper function group_get_extended_data(..) to htdocs/lib/group.php
- Fix previous bug failure due to button class change for submit
- Styling for table changed to to "break-word" to stop truncating words
- overflow of buttons controlled + responsive results heading+footer
- button moved to first level of form to stop button cutting button on
small screen
