Trying to debug fprops_triple_point for Toluene with pengrob correlation. Something strange is happening with fratio.

Added some C tests for sat and solve_ph routines.
Added parameter 'source' to fprops_fluid, to allow data with a particular source to be specified (optionally). This allows forced testing explicitly of the RPP data even when Helmholtz data is also available.
Tweaked some convergence parameters in sat.c and solve_ph.c to get convergence across broader range of parameters for more fluids (more testing required).

Merged (copied) fprops2 branch to trunk. This copy overwrites the trunk version of fprops,
and history is preserved via the fprops2 sequence. I hope that's OK...

Deleted sat2.c and sat2.h, that code is not being used anywhere in ASCEND/FPROPS now. REFPROP algorithm replaced by Akasaka approach.
Moving sat3.c code into sat.h.

numerical algorithms for saturation curve. algorithms are based on those used by REFPROP, but the code is a new implementation. hoping that this is all legally correct; please let me know if there are any issues -- JP.
