Blobstore changes

Should be the version from our last demonstration
A new font to maybe try out

CSS temporarily set to the new font. Can run AppEngine locally to see
it.
Cleaned up CSS
Removed flashy CSS3, and added room for search bar

We still need to add a search bar feature, but the page looks more like
what I think it should look like in the end
Fixed login link
Merge branch 'master' of https://github.com/MiguelDickson/chalkboard
Rough draft of adding a new course

We still need to work on the CSS to fix this up (its missing ID tags I
think is the main issue).
Added templating to print course keys for now

Ideally this page will print out a list of all the courses the professor
has, with the option to add new courses.
Added a very basic page to be used to edit courses
Redid data model.  Big overhaul to handle courses

This is still a bit buggy.  The code more-or-less works without
crashing, but it is still in an Alpha stage for now.
Added code to display course name/URL in list

Instead of only showing the key, I now display the course URLs and names
in the Instructor page.  There are still a few bugs with the GET/POST.
Change in regex

blah
Added course page (when you click on a course, it populates based on course info)
Course page grabs course info to display.
Changed course URL to course_id.
fixed minor typo
Updated login/logout in header (top left of screen)
Fixed redirection issue with creating courses
Fixed redirection issue issue/typo
Redirect after course creation for POST protection
