2D interactions

[youkha]

The notion of symmetry should be enforced in a general way but this is a deep issue as it shoudl be a core functionality in 3D as well as 2D.
However there are bugs - for example in some cases if there is an interaction A-L there the symmetrical A'-L' should be there
example: 2 ligand in symmetrically equivalent positions show different links (interactions) in the 2D cartoon:

The 2D interaction cartoon seemed symmetric to me.
