Basic user profile page, also bios
Say we have the user cwebber, and we want to find out all about
cwebber! A little bio, what are the latest images, etc.
[http://mediagoblin.example.org/\ :sub:`cwebber/](http://mediagoblin.example.org/`\ cwebber/)
Should show a few of the latest images (not all, that's
[http://mediagoblin.example.org/\ :sub:`cwebber/gallery/](http://mediagoblin.example.org/`\ cwebber/gallery/)
) and also a personal bio, if a user has provided one.
should allow me to change my profile (for now, just adding a simple
bio is fine). It would be great to wrap that work into this
