Notify vendors about conflicting modules

[bskqd]

While parsing the files we can encounter files that are already available in the save-file-dir (which means that they have already been parsed before) and the hash of the two modules at this point is different, so we have to understand if these modules have only formatting changes (different quotes around strings, whitespace changes, additional comments, etc.), or the content of these files is different and if the content is different then we have to notify the vendors that this is a bad practice, and they should create another revision for such changes.
