QM thermo looks for MOPAC2009.exe file, but should now be MOPAC2012.exe

[rwest]

Having the program name hard-coded is not very future-proof, as MOPAC2009.exe no longer runs (it just tells the user to upgrade). This may happen again when the next major version is released.

A temporary work-around for users before this issue is resolved (and made into a release) is to rename or symlink your MOPAC2012.exe program into MOPAC2009.exe so that RMG (or ThermoDataEstimater or whatever) can find something where it expects.
