Default dataset change

Getting a bit fed up at the moment because I spend hours and hours of bug hunting in Aecosim...

There have been numerous discussions on communities about Bentleys inability to provide proper support for costumers outside the US. 
In addition there I do have a bunch of Service Requests that are not reproduceable by Bentley staff, because they just test against US dataset.

In my opinion the core problem of the whole thing is that BuildingDesigner.cfg has this definition.

TF_DATASETNAME : Dataset_US

This should be changed to a metric dataset instead.
