Syncing 3_0 and 4_0
Updating embedded calendar to follow http://software-carpentry.org/bootcamps.ics

I made a Google calendar on the admin@software-carpentry.org account that
follows our generated calendar file and switched the embedded calendar to
point to that. I also added some margin space to the bottom of the map div
to put some room between the map and calendar.

Removing some items from the embedded calendar.

Specifically the title, print icon, and calendar list menu (since we have
just one calendar).

Adding a link to the calendar feed below the embedded calendar.

I also added an swc-blue-bg class to swc.css that sets the background
color to SWC Blue. It can be used in conjunction with the Bootstrap label
class to make an SWC Blue label. And I updated the footer labels to use it.
