Use the "account" link at the bottom of the page to login. This is just a functional skeleton. You can change your name in the Edit Profile area. The other two tabs (Gameday and Follow) don't actually commit to your user account yet.

This was a lot easier to implement than the previous attempt.

Features:
* Account registration - User needs to fill out a form (WIP) before having their account saved to the datastore and being allowed to access account pages. This way, we can get basic information.
* Profile editing - Right now you can only change your name. It should be trivial to add fields. Discussion on what fields/settings we want available would be nice
* Administration - Your basic listing, details, editing, and deletion (modeled off of the events management)
* Custom user greeting template tag `{{greeting}}` which uses the user's name, or their nickname/email if no name provided.

Still needed (not necessarily in this pull):
* Banhammer
* Integrate with content submission (crediting)
* Add additional profile fields and site settings
* ACL (?) - Being able to disable video submission for abusers, allowing users to submit/edit their offseason events, etc.
* Everything else not yet implemented from [the wiki](https://github.com/gregmarra/the-blue-alliance/wiki/Users)

This will resolve #546
