Feature/unique exec suffixes
The mixed naming/numbering approach already implement for __name is now also applied to __exec_suffix. This implies:
- moving the code to a separate module that is used from both places
- rewriting the main part of metaIni.py to reuse static_metaini.py instead of mimicking its behaviour
I somehow lost track of teh corner cases that should be treated. I therefore propose this merge request to be treated as a real such with you testing and requesting fixes before the merge.
PS: I am not sure but maybe you have to cherry-pick 9770e32d in order to make the branch work. I accidentally broke master last week.
