[sugar] Release report

[Marco Pesenti Gritti]

Hello,

I added a release report script to sugar-jhbuild. It assumes the
changes I just announced to the code review process. Let's use it
starting from Sucrose 0.81.4. Make sure to tag releases in as vXXXXXX
to make sure this works.

It will also generate test cases. I'm not sure where is the best place
to put those. We can just put them in the announce mail and the
release notes as a first try.

Please report any issue you run into with it.

Marco
