Multi-phase solvers: Improved handling of inflow/outflow BCs in MULES

Browse Source 
Avoids slight phase-fraction unboundedness at entertainment BCs and improved
robustness.

Additionally the phase-fractions in the multi-phase (rather than two-phase)
solvers are adjusted to avoid the slow growth of inconsistency ("drift") caused
by solving for all of the phase-fractions rather than deriving one from the
others.
