Add 'edit' page for patrons

Add a page where patrons can edit their
data stored in Copper Heart.

Right now all people can do through the UI
is add new things to the database.
Edit: Allow the deleting of things

It's fun to be able to delete things as you
no longer need them, or make a mistake.
Edit: Allow editing of 'who' data

Add fields for editing the visible,
full name and the 'what are you working
on right now?' data.
