Feed layout complete with some minor bugs

Bugs:
* Name overlay covers title
* The counts on likes, comments, and clips need to be spaced
* fundraising post needs a company in the view
* For post creation, submit and cancel buttons need to be below the
link and tag fields
* Across the board support for pictures
User profile is complete. Database table for Messages. Small bug fixes.

Couple of things for Shawn:
* Remove ability to remove classes under Education when vieweing a
user's profile. This should fix the error where a user who's looking at
someone else's profile can remove courses.

* Similarly, a user can remove another user's skills and interests.
SHAWN PLS

* User's shouldn't be able to edit their emails in the personal section
of the profile. This is their username and cannot be changed.

* Press enter to login in the landing page

BUGS
* dashboard_overview.html is really messed up right now. It needs to be
fixed at some point.
