Modified revert of commit 6c6f777bd5.
- The "alphaContactAngleFvPatchScalarField" occurs in several
places in the code base:
- as abstract class for two-phase properties
- in various multiphase solvers
To resolve potential linking conflicts, renamed the abstract class
as "alphaContactAngleTwoPhaseFvPatchScalarField" instead.
This permits potential linking of two-phase and multi-phase
libraries without symbol conflicts and has no effect on concrete
uses of two-phase alphaContactAngle boudary conditions.
