VERY early draft of user management via sudo
Note on username validation
CAS works, could be prettier
It's dangerous to go without itsdangerous
A bit of a frontend
Oh, and add the register template
Remove pycas
Clean things up, fix a few bugs
Pipe data in correctly
Add add_ssh_key script
Run sudo non-interactively
Check whether the user already has an account before allowing them to sign up
Add rudiments of 'flow' and 'ui'
Factor config into a file
New ssh key regexp
Make add_key only accept POSTs
Some work on scripts
