Added .gitignore

Added a .gitignore to our project
Fixed html inheritance

I recreated main.html that was lost in first repo.  I think added back the style and nav bar to base html and set main to inherit from base once again.  I also had to create a new view and url link for main.html.
Fixed generic error and js

Forgot an import statement in views that imported the generic view from django.  This was preventing main from loading at all.  Also forgot to add a javascript "script" line to base html.  This allows for javascript to work on the pages.
