Update the readme.
Highlights:

Remove information about Eclipse, it's out of date now.
General formatting and text tweaking.
Update dashboard buttons.

Specifically, changed Blackboard icon to a more generic Courses icon in
preparation for Canvas support.
Update Blackboard indicator icon in course list.

This also required a bit of minor tweaking to the Canvas indicator to make
sure they aligned correctly with each other.
Handle Canvas courses with non-standard term names without crashing.

If a term name is not the standard "Season 20XX" format, then we use the
start_at field to try and figure out the semester of the course. If that
doesn't work, we just sort the course to the bottom of the list.
Fixes #12.
Remove unused (and always null) fields from Term pojo

Bring canvas branch up to date with master for beta release.

I'm still not really sure of the best way to handle long-lived branches
like this. I'll want to merge it back into master at some point, but
maybe I should have a permanent beta branch.
