Added basic editing functionality for Cylinders and Weigthsystems

This patch adds basic editing functionality for Cylinders and Weigthsystems,
it still doesn't use delegates to show the data to the user in a better
way, and it does not take in consideration user preferences yet, but
it's a starting point.
