new commits mailing list

[Michael Bedward]

Here is a new mailing list that you can subscribe to if you want email
notices of commits to the jaitools and jiffle repositories:

https://groups.google.com/forum/?fromgroups#!forum/jaitools-commits

This replaces the jai-tools-svn list.

I'm not sure if I've got the service hook thing set up properly at the
github end. Also google groups marked the first few commit messages
from me as spam :)
