adlc command line app is now working, altough not heavily tested. However, main BMM schemas load correctly, tested archetypes parse, compile and flatten correctly.
Update adlc to use gobo release on gobo @ github. This includes parsers regenerated by the new versions of gelex, geyacc. To have a build environment working properly, it needs:

- Gobo @ https://github.com/gobo-eiffel/gobo cloned, and a system env var $GOBO to point to that
- run $GOBO/work/bootstrap/bootstrap.bat as 'bootstrap.bat msc ise', possibly run vsvars32.bat or equiv first, if not already in boot up env
- the adlc .ecf now points to a single gobo library .ecf which sets void-safe mode on the kernel lib but not elsewhere (this .ecf will be added to the openEHR project), and for the rest of gobo, normal 'cluster' inclusions, since the other libs are non-void-safe at the moment.
