#1 - Add placeholder content

Following steps from:
https://code.google.com/p/course-builder/wiki/RunMultipleCourses

Added 6 new courses (iOS, android, web, etc) and imported content from
my existing ME430 course builder class.  It is based on version 1.5.1
so it will likely need various updates.

Nothing actually works yet as I have not yet modified sites.py to
inform GAE of the files, just starting the ball rolling by adding a ton
of files.  The real courses only have one file which is not modified.
ME430 might “just work” :)
