Display website url in Participant list view in django-admin.
First stab at layout using bootstrap classes, and some related styling.
Remove percentage padding as this breaks some elements.
Add elum_top.png bar to top of text boxes using css background
properties rather than img tags. Less code, and it displays right at the
top of the box (as in mockups) rather than several pixels down from top.
Made all hardcoded hrefs use url template tag instead.
Add vertical spacing between events on participant detail page.
Fixed displaying of event days in participant detail screen, and
formatted the event labels the same as category filter label.
Merge branch 'master' into participant_views_5
Switch to using a variable colour instead of hardcoded for label on
category filter.
Synched all of this branch's styling changes from
