Closes #14

Review would be appreciated, but are probably not going to happen :cry:

Per our plan, we only have admin/non admin accounts. It would be a little bit more work to add multiple permission levels (view, write, admin, perhaps)?.

Is it worth adding a permission heiarchy, or should we just have a admin bool = true;

Opted for the permission heiarchy, since I figured out how enums work in go (they dont).

Next step is allowing permission levels to change and user change of passwords (and help text)

Should be feature complete at this point. Please let me know if you see any bugs.

Should be ready for the video demo at this point.

Here's a short demo video. We can easily take snippets from here. Right now it's 2:30, so we need about 1 more minute of demoable material (which should be easy).

Youtube decided to horribly compress my 3mb video file, so here's the version that hasn't been corrupted by google https://transfer.sh/Ar1du/recording.mkv

This is probably never actually going to get reviewed so merging. Please let me know if you find problems.
