QUDT Release v2.1.41

Updates include:

• Augmented our units URI naming rules (see Rule 6 on our Wiki) to handle the case of "thousands of cubic feet", which is of course distinct from "one thousand feet, cubed". The former has the URI unit:KiloCubicFT. The latter is unit:KiloFT3.
• Added the cost unit CHF/KiloGM, meaning Swiss Francs per Kilogram. While this could represent a slippery slope in terms of number of units (all currencies combined with all units!), we intend to add them upon request for popular use cases. (Thanks @tpluscode)
• Updated the QuantityKind referenced by LB_F-PER-IN to be the skos:broader concept EnergyPerArea instead of SurfaceTension (Thanks @mgberg)
• Added the QuantityKind GaugePressure to support the common use of measuring pressure above ambient atmospheric pressure. A Quantity in QUDT having a QuantityKind of GaugePressure would typically also assert the value of qudt:isDeltaQuantity to be true, indicating that the value is a difference between two pressures. (See the documentation here). Thanks to @TKaluza for suggesting this.

And as always, a big thank-you to all of you for bringing many of these issues to our attention, and even better, for providing submissions to extend the coverage and capabilities of QUDT!
