Changes to support new uri format ( e.g. one that doesn't depend on old logical name -> function name mapping ). Briefly theses changes are temporary in that they basically make sure that the logical name and function name are the same. From the point of view of the parcel-descriptIon.xml the logical name is ignored. Also updated the ExampleSpreadSheet.scx with new binding to reflect the changes.
Reorganise package and directory structure of Java classes to better reflect
the UNO interface hierarchy being implemented. Move ParcelDescriptor class
from idesupport package.
