Update .ecf file to ISE-based library inclusions.
Further modifications to get a working compile and finalisation. Basic tests show correct functionality. Note that a combination ISE library statements and cluster inclusions for gobo had to be used.

The compiler version is interim build 7.2.9.1078 which has some short term changes to gobo kernel to make it compile under 7.2

Note also that void-safety had to be turned off on the root (i.e. app) cluster to prevent a compiler crash which still has not been solved.
Interim commit of all void-safe GUI changes so far before changing directory structure so that void-safe can be on some app cluster classes, but turned off on the UI classes.
First stage of UI cluster re-arrangement
