Merge branch 'confab' of https://github.com/cowsandmilk/openbabel into confab
Porting commits from the original Confab:

torlib.txt, rotor.cpp:
* Using Graph Symmetry, remove symmetrical torsions.
* Reduce the torsions by incorporating graph symmetry. Note that torlib.txt trumps this in the case of CX3 where X is a halide
* Force Forcefield setup always. IsSetupNeeded() fails silently in some cases
