Added failing unit test for issue #163 in transport data estimation

The Joback database of groups to estimate critical point properties
cannot cope with beneze type bonds.
Merge branch 'master' of https://github.com/bbuesser/RMG-Py
Remove solvent(water) from minimal example.

Minimal should be just that - minimal.
This hides issue #165
Default 'make' target includes QM

'make clean' would remove symmetry program, and 'make' would not recreate it.
This was frustrating. The target 'all' should be just that: all.

I mane a new target, 'noQM' in case you don't have RDKit with InChI support:
`make noQM` will let you build without QM stuff.
Update Makefile with liquid phase example 'eg3' target
