WORK IN PROGRESS

From user's point of view (just a few):

* Menu item in StX active only when bundle can be created (multiple changes are present)

* Automatically takes all changes and gives a user which ones to use in the one specific bundle being created

* The commit message should be pre-filled with the information, which packages (changesets) are being committed in this bundle; not to forget any

* Is there a bookmark possibility with the hg bundle?

* Amend to bundle
