FluidAPI Continued

[amirroth]

This is a continuation of this PR which created an object-oriented API for FluidProperties. This PR propagates this API to Water and Steam uses outside of plant. The next PR will propagate the API to plant.

There are no diffs as expected, this is just a "simple" search-and-replace PR. If I knew Python as well as @Myoldmopar, I probably could have done this using an actual search-and-replace.

Why did this not show up in my inbox? Also, this doesn't jibe with the successful test report below. Is this stale maybe?

5ZoneAirCooledConvCoef_VSFan shows this error for develop and this branch (this type of error should not be a fatal):

** Severe  ** Iteration limit exceeded in calculating variable speed fan powered box 1st stage heating fan speed
**   ~~~   **  Environment=RUN PERIOD 1, at Simulation time=09/30 06:27 - 06:30
**  Fatal  ** PIU control failed for AirTerminal:SingleDuct:ParallelPIU:Reheat:SPACE4-1 VAV REHEAT 

AbsorptionChiller_Macro failed to run, for some reason, in develop and this branch (a regression tool issue?).
ShopWithPVandLiIonBattery failed in this branch with a sqlite error:

SQLite3 message, sqlite.err open for processing!

So I don't think these failures are related to changes in this branch. I'm not sure why the VSFan file runs on Linux, or if it even did.
