Added profs to the search bar

Should be fairly straightforward, I basically just went through and added `profs` to any spots that only had `courses` and `friends`
Also, if we're unsure how long it will take before we can do (2) (and 2 is also sort of pre-requisite on being able to match an official full professor name like "Edward Dupont" with the names we have stored ("Eddie Dupont")), you can also just do (1) for now. Stick that code in `aggregator.py` and save departments taught to a list field on professor. Then when (2) is ready we can convert then.
