[transform.vat] Simple transformation service for adding VAT to amount

[jlaur]

I'm working on a small and simple transformation PoC for adding VAT (Value-Added Tax) to a given amount based on configured system country. The general idea is to avoid having such duplicated logic/databases in bindings, and for convenience so that users won't have to manually configure this over and over again.

JARs:

• org.openhab.transform.vat-4.0.0-SNAPSHOT.jar
• org.openhab.transform.vat-3.4.3-SNAPSHOT.jar
