Contribute: 'ready', not 'good to go?'

'good to go?' doesn't feel right.
Let's try 'ready' instead.
Version 0.5

There's now an entrance / home page, and
a contribution flow that mostly makes sense.
There is a thank-you page, albeit empty.

Things can be edited and rearranged. Patrons
can see who they're contributing to. There's
an about page that starts to explain what's up.

Heart favicon.
