Basic scraping and processing to show professor contact info

This does not take in to account names like "Eddie Dupont" which we currently won't match. A future PR will implement a feature to make the connection between Eddie and Edward. Also note this only shows the info on the prof page, and not the course pages they may be mentioned on. Though that could be added to this PR if you guys want.

I forgot to mention it when during your original PR for the prof page, but we should make use of the `Prof` Backbone model we have rather than adding stuff directly to the `pageData`.

It's probably too large of (and tangential) of a change to make this in this PR, but could you add a TODO here that we should use the Prof model? And also, could you file a github issue for it? Thanks!
