Supporting VRMS

[fyliu]

VRMS has several user stories that we can try to support. They're not in the order that we want them. We should start with user registration and login. Then filling out profile data during "onboarding", then adding projects as brigade admin and adding users to projects as project lead, then creating events.

Permissions control is pretty high priority to do the above things. I was working on that before switching to making guides for new people coming on board. Feel free to reassign it to someone else.
