Title: System Groovy Script ChoiceListProvider

I have implemented a ChoiceListProvider which uses a System Groovy script to get the list of choices from the internal Jenkins model. I use it to get a list of jobs, which starts with an application prefix and end with the suffix "trunk". With the Jenkins Groovy Plugin I can run a System Groovy Script which clones a job and modifies the SVN URLs to a branch URL automatically.
It would be great if you could merge the code and release a new plugin so that the system groovy provider gets part of the original plugin.
