Moved the print how many lectures to inside loop so if loop stops because of going over the quota, we know how many have been added
Moved back how many lectures have been added; added print index of module

since we don't need to know the lecture index, but the index of the
module (the parser works by reading the module and not the lecture)
Debugged parse on module index; upsize font for social widget; changed tweet button from widget to link
Add go home button
Design updates for search2.html
Added loading spinner for search
Fix horizontal overflow, search button, layout
Changed @import to link href for better performance
Wrote unit test skeleton in tests.py
