Update real interaction plugin

[superstar54]

Update

• update Rigid Body to support Batoms 2.2 version
• rename the old force field panel to ASE force field panel. This panel currently not working.
• add a new panel to support for OpenBabel when editing molecule

How to use it?

For rigid body:

• click Rigid Body
• select one batoms object
• move mouse, now all batoms objects are treated as rigid body.
• press ESC to exit.

For force field:

• select a batoms object (select the atoms, not bonds etc.)
• click Force field on the panel.
• select the batoms, go to edit mode, and select atoms
• move the mouse, and the molecule will optimize in real-time
• press ESC to exit.
