* remove contributors from package.json in favour of AUTHORS
The contributors section of our package.json is _very_ long and
manually updating can (?) be a pain.
I took a leaf out of nodejs's book and copied their update-authors
script [1].

* remove some of my many emails
* add a couple more mail mappings
* get lint passing
* add instruction to update-authors
