It would be great if it were easy to set the description over http, so events
that occur that might change something about the build can easily update the
description for everyone to see! An example that would be useful here is when
deploying a branch, update the description of the project for that branch with
the revision, timestamp, and environment it was deployed to.

Attached is a patch which implements this! Now you can easily do:

wget http://localhost:8080/job/test/description --post-data="description=new"
