Showing registration status for boot camps on index page
* Merging Trevor King's modifications to boot camp compilation to show open/restricted status.
* Adding optional metadata 'registration' to boot camp pages to show if they are open or restricted.  If metadata not present, boot camp registration hasn't started yet.
* Changing format of boot camp index page accordingly.
This should fix issue #295. It doesn't matter where in the template the pageclass identifiers are so long as they're there.  They shouldn't come before the inclusion of the base template because then they are rendered before the doctype declaration, which confuses IE.
