Antioch now uses kg/mol for molor mass.
Updated kinetics regression for Antioch.

This is because of the slight change for the universal gas constant
conversion to calories (see discussion in #24).
Update regression test for new Antioch

Has to do with updated gas constant value. See discussion in Antioch
issue #24.

Finished updating reacting flow regression tests

Has to do with updated gas constant value. See discussion in Antioch
issue #24.
Add fan blades, cut off time integration
Clarify "radial" direction, fix lift direction
Add AveragedFan regression test

It's hard to get something easy to "eyeball norm" in 2D, but the 3D
example seemed okay, and this 2D test runs fast enough to be part of
"make check" and help us catch regressions.

Add AveragedFan regression test
Bumped minimum Antioch version

This is due to the 0.2.0 release of Antioch which updated the
conversion factor of the gas constant which, in turn, required
updating the "gold" regression test restarts.
