Rename the ACN part in asn2aadlplus
in DataView.aadl, there was a part referencing all ACN files, however the AADL identifier was based on the file name. In the case of several ACN files with the same name but in different folders, we could have duplicate identifiers in the AADL file. This patch makes use of the module name instead of the filename for the identifier. The module name must be unique.
