Henry Weller b167c95f19 compressibleInterFoam: Completed LTS and semi-implicit MULES support
Now the interFoam and compressibleInterFoam families of solvers use the same
alphaEqn formulation and supporting all of the MULES options without
code-duplication.

The semi-implicit MULES support allows running with significantly larger
time-steps but this does reduce the interface sharpness.
