Move the "href shift" within the function itself

Change Request

Description

In v4.Fluid href*Xh20 is subtracted from the enthalpy. This is done to have the same reference for the enthalpy of water, both in WaterSteam and in FlueGases (e.g. when sending some vapor from a WaterSteam.Tank to a FlueGases.Volume.

Proposed Solution

It should be possible to improve how we deal with this in a couple of ways:

• Moving the href correction directly into the property functions.
• Changing the ref in the call to used tables (used Media).
