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.

Like mentioned above, if you use BeautifulSoup, you no longer need to match for the `<b>` and `<i>` tags.

For regexes, you should prefix prefix the string with a `r` so `'\s+'` becomes `r'\s+'` for example. Read the first few paragraphs of [this page]() for an explanation.

Also, depending on how complex the updated regexes are, you might want to consider using [verbose](https://docs.python.org/2/library/re.html#re.VERBOSE) regexes and adding some comments about what the different parts of the regexes match.
