Remove hardcoded references to HackMIT

[SheaBelsky]

There is an Angular variable {{ EVENT_INFO.NAME }} which contains the user-specified name of the hackathon. There are a few instances where this is not respected, and is instead written out as HackMIT. To make it easier for others to fork the project, these references should be changed.

I can submit a PR to do this. Just wanted to make an issue for it too.
