Hi Tom,

I went through the change bars in the EJBQL chapter of the PFD version
to find areas where we need to update the EJQBL compiler.

- More restrictive path expression in JOIN clause.
- Lexer support for numeric literals.
- Rename some parser rules to match the BNF.
- GROUP BY now allows entities.
- The SET clause now allows relationship settings.

I need to do some testing in oder to see the impact of the GROUP BY- and
SET-clause change. It might be only a minor change in the parser, but
I'm not sure about the runtime.

Regards Michael
