I chatted with Asheesh on IRC today and asked him to look over the
contributer howto. He had a lot of thoughts and I factored most/all
of them in. It's much better now.
* lots of changes to the contributing howto from Matt, Greg, Will, and
Chris
* adds references between the contributing howto and other chapters
* adds a design decision regarding copyright assignment
* fixes some typos
* tweaks some language issues that occured because I took Chris'
stuff out of the context of the original READMEish structure
* ditches installation for deploymenthowto and hackinghowto
