New maintainer for the Casetracker module

Peter Decuyper (zero2one) is to be the new maintainer of the Case Tracker module. He has demonstrated a keen understanding of the module, a viable roadmap, and a resolve to maintain it, improve it, and be the primary point of contact for orchestrating the efforts of other contributors.

I will offer my own resources and work with him to guide the direction of the module. I have already discussed with Anthony Oliver who worked on the Summer of Code improvements, and we will be incorporating any relevant additions he made (http://drupal.org/project/xcasetracker).

Thank you Peter!
