Default 'make' target includes QM

'make clean' would remove symmetry program, and 'make' would not recreate it.

`make noQM` will let you build without QM stuff.
Update Makefile with liquid phase example 'eg3' target
Remove print line for transport objects when saving Transport file.
Add logging statement when saving verbose chemkin file.

Otherwise there is a duplicate "Chemkin file contains X reactions"
statement without explanation.
