[COOT] new coot function

[Simon Kolstoe]

I asked Paul about this a couple years ago and he said it wasn't high  
priority at the time, however a functionality in TURBO-FRODO that I  
used to really like was the option to break a bond and then rotate/ 
translate just a section of a residue/molecule. This is particularly  
handy when building in larger ligands. Is this something that would be  
easy to enable in an upcoming version?

Thanks,
Simon
