Add deb_all and mock_all tasks to the pe:jenkins namespace

pe:jenkins tries to call out to deb_all and mock_all, which didn't previously
exist in the pe:jenkins namespace. This commit adds them to the list of tasks
to be dynamically generated in the pe:jenkins namespace to avoid this problem.
Merge pull request #124 from haus/add_pe_jenkins_tasks
