Set mime type for BBoxDataOutput to text/xml
Bugfix and test for RawData BBoxOutput

The XML representation of the BBox was not well formed if requested as
RawData.
Introduced AbstractLiteralDataBinding

This abstract class holds the uom parameter and respective getters and
setters. Every LiteralDataBinding extends the abstract class to have
access to the uom parameter. Some minor changes were necessary in
GenericRProcess and AbstractSelfDescribingAlgorithm.
