Added carousel, began calendar

Added carousel to front page.  Made floating navbar.
Added seperate layouts for other pages.
Began work on brief calendar
 - could be a feature on main page
 - and/or sidebar on other pages
Finished Carousel & Calendar, updated bootstrap

Changes:
 - updated bootstrap to v3.0 (from v2.3.2).  Needed to change some navbar
   tags as well as `span` to `col-log-x`, and other minor changes.
 - Finished Carousel feature.  Need to add more content
 - Finished Calendar.  Now shows up as sidebar in extra pages, and as a
   mini-column underneath the carousel on the main page.
Merge pull request #4 from rockames/feature/calendar
