Add a "description" field for plans

Please add a long text field at the plan level in which a detailed description of the plan can be added. This could also be occasionally used to describe the state of the plan.

Here's my use-case. Various builds in our project have ridiculously detailed names. I'd love to shorten them to make them more readable. I'd move some of the details to the plan's "description" field but there isn't one.

To work around this I'm probably going to have to put the information into a wiki page.
