notmuch vim patches

[Ian Main]

For those who are interested, I've created a fork of the official(?)
github repo that contains all the patches I've worked on so far.
For those using notmuch-vim this would be a much easier way to try
out the new code.

I think it could be useful to get feedback here on what people think.

I'm starting to realize that I could default to using 'enter' to both
open URI's and view attachments.  Any other ideas welcome.
