Bootstrap3

- Removes all Bootstrap 2 files, replaces with Bootstrap 3.1.1 (minified CSS etc., default download from getbootstrap.com as opposed to any customisation or use of .less files)
- Gets Glyphicons working again
- Improves UI around simple and advanced search - no more reset button unless you have a search block!
- Proper Bootstrap 3 styles and HTML structure for log-in page, Admin users list, new user, edit user pages
- New Bootstrap 3 navbar (static with all options in the admin bundle, functional in WOSE)
- Logo in footer repaired
- Pagination block repaired

However - this work is me fixing/upgrading what I can, so if there are pages I can't find or don't know about, they may still need work doing. Also have not done much in the way of cross-browser testing as it's really out-of-scope - if it looks/works well in Bootstrap it will still be fine here, if not it will need looking at again.

Please can whoever reviews this give the changes a once over and let me know if there's anything I've missed?
