Add parsing logic to include an input transformation (in:<inTransform>) and an output transformation (out:<outTransform>) to the parameters that bindings can understand.

This data is currently not used, but is pushed down into the BindingConfigs for future hookup.

These named transformations will be instantiated from the standard openHAB TransformationService, so you'l' be able to use things like MAP(...) to perform static mappings (1=ON,0=OFF etc), as well as XSLT to extract elements that might be in packed <XML> strings within StateVariables (as the MiOS Sonos binding does)
