[Oberon] Intermediate scopes in Oberon-07

[Jörg Straube]

I only declare TYPEs if I use them several times (and as base RECORD of a type inheritance hierarchy)
To be able to use them several times, I normally declare them on module level.
With the one exception I mentioned in an earlier mail: local redefinition of parameter TYPEs only used in that procedure.
