79ff91350e rhoPimpleFoam: Improved support for compressible liquids 
See tutorials/compressible/rhoPimpleFoam/RAS/squareBendLiq for exapmle

pimpleControl: Added SIMPLErho option for running in SIMPLE mode

with large time-step/Courant number and relaxation.  With this option the
density is updated from thermodynamics rather than continuity after the pressure
equation which is better behaved if pressure is relaxed and/or solved to a
loose relative tolerance.  The need for this option is demonstrated in the
tutorials/compressible/rhoPimpleFoam/RAS/angledDuct tutorial which is unstable
without the option.

99c992d65c rhoPimpleFoam: Added support for transonic flow of liquids and real gases 
Both stardard SIMPLE and the SIMPLEC (using the 'consistent' option in
fvSolution) are now supported for both subsonic and transonic flow of all
fluid types.

rhoPimpleFoam now instantiates the lower-level fluidThermo which instantiates
either a psiThermo or rhoThermo according to the 'type' specification in
thermophysicalProperties, see also commit 655fc78748
