New features for Words and Media

New features include:
1 ) A "Words Used" floating box that tallies up the words used in the 311 requests in the current view/search.
2 ) A "Media" window that cycles through the images used on 311 requests in the current view/search.

These features were created durring the Baltimore Hackathon (www.baltimorehackathon.com)

NOTE: These are initial working versions of these features, a bit of testing and code cleanup needs to happen still.
