Changes:
-Remove title field from poll; use post content instead. There was no reason to have both the poll title and post content, so to make it easier to maintain I changed it to only be the 1 field. I verified this with @MirandaZhou to make sure that would be fine.
-Actually implemented all of the media stuff. Since the mobile PR had to deal with these end points a lot, I decided now would be a good time to rewrite this properly and get rid of the legacy code.
-Added the ability to delete media from preexisting posts.
This goes along with mobile PR https://github.com/CGUC/skybunk-mobile/pull/202
