disconnect_wiggle

As requested by a few Shake and Houdini artists, a little python script to disconnect a node by shaking it.

To install, copy to your plugin path and add 'import disconnect_wiggle' to your menu.py.

Update 1.1: Added a fallback for the whole function to catch occasional error messages which didn't affect much

Update 1.2: Undo now works, thanks to Cuco Bures for pointing me in the right direction.
