[stp-dev] BPMN updates commits for Ganymede M3

["Hugues Malphettes" <hmalphettes@xxxxxxxxxxx>]

Hi,

Updates of the BPMN modeler code have been committed for Ganymede M3.

The fixes are mostly related to:
- undo, redo
- copy-paste
- a new tool to "insert or remove" horizontal space inside a pool.
- ability to re-connect existing edges to different shapes.
- shape and labels layout improvements
- there are also refinements of the extension points made for
validation, context menus and drag-drop integration to the modeler.
Those are not backward compatible. Let us know if you need help
migrating your code. We are not aware of a huge crowd of developers
using them so hopefully the impact will be minimum.

Localization of the message strings is due for Ganymede M4.

Cheers,
Hugues
