- procedural: bugfix in "Barendregt convention" test

- procedural: bugfix in "Barendregt convention" test
- library/logic/cprop_connectives.ma: reorganized.
notations must immediately follow the definition they refer to (or else another
definition can use them in the reconstructed version of the file)
- core_notation.moo: added a notation for non-functiona 'exists
eta-expansion (not a CIC conversion) should be avoided exp. if the rendered
text must be reparsed (ie. during the reconstruction)
"default" notation facility reactivated in parsing mode since it is not
equivalent to the separated rules (they cover eachother).
The bug is in the rendering mode
- applyTransformation: debugging information added (commented)

logic/cprop_connectives.ma reconstructed and compiled !!
