phaseScalarTransport: Improved interface and documentation

Browse Source 
This function now looks up an alphaPhi field by default and exits with
an error if the field cannot be found. In order to solve for alphaPhi a
new 'solveAlphaPhi' switch has to be set.

The documentation has been updated to reflect the fact that the VoF
solvers now store all the alphaPhi fluxes necessary for a in-phase
equation to be constructed.

The phaseScalarTransport function has been added to the damBreakLaminar
tutorial.
