Added the interfacial pressure-work terms according to:

Ishii, M., Hibiki, T.,
Thermo-fluid dynamics of two-phase flow,
ISBN-10: 0-387-28321-8, 2006

While this is the most common approach to handling the interfacial
pressure-work it introduces numerical stability issues in regions of low
phase-fraction and rapid flow deformation.  To alleviate this problem an
optional limiter may be applied to the pressure-work term in either of
the energy forms.  This may specified in the
"thermophysicalProperties.<phase>" file, e.g.

pressureWorkAlphaLimit 1e-3;

which sets the pressure work term to 0 for phase-fractions below 1e-3.

For particularly unstable cases a limit of 1e-2 may be necessary.

The best of the current options is to use the latest version of
exuberant ctags (which has a new C++ parser) to generate both
declaration and definition tags.

gtags works to some extent and provides additional information about the
function signatures but the C++ parser is not accurate and misses scope
information.  gtags can be used with the ctags parser which is effective
but looses the primary advantage of gtags being able to provide function
signatures so support has been switched-off by default.

ebrowse does not appear to be very useful for traversing the OpenFOAM
class tree and the support has been switched-off by default.

This reverts commit f7996e45.

ctags-exuberant is now the more common name for the exuberant ctags
program.

Commented-out gtags as it is not commonly available.

Added 'READ_IF_PRESENT' option to support overriding of the default BCs
for complex problems requiring special treatment of Udm at boundaries.

In many publications and Euler-Euler codes the pressure-work term in the
total enthalpy is stated and implemented as -alpha*dp/dt rather than the
conservative form derived from the total internal energy equation
-d(alpha*p)/dt.  In order for the enthalpy and internal energy equations
to be consistent this error/simplification propagates to the total
internal energy equation as a spurious additional term p*d(alpha)/dt
which is included in the OpenFOAM Euler-Euler solvers and causes
stability and conservation issues.

I have now re-derived the energy equations for multiphase flow from
first-principles and implemented in the reactingEulerFoam solvers the
correct conservative form of pressure-work in both the internal energy
and enthalpy equations.

Additionally an optional limiter may be applied to the pressure-work
term in either of the energy forms to avoid spurious fluctuations in the
phase temperature in regions where the phase-fraction -> 0.  This may
specified in the "thermophysicalProperties.<phase>" file, e.g.

pressureWorkAlphaLimit 1e-3;

which sets the pressure work term to 0 for phase-fractions below 1e-3.

Previously the inlet flow of phase 1 (the phase solved for) is corrected
to match the inlet specification for that phase.  However, if the second
phase is also constrained at inlets the inlet flux must also be
corrected to match the inlet specification.
