1377 - Blacklist dependencies from SCM tracking

Git excludes dependencies from commit. 
Mercurial just shows a warning because it doesn't support excludes on commits. Just hgignore
because you need to check if the module exist in a list of strings. `if not module in exclude_files_content` always return false. Maybe something like `for module in exclude_file_content: if module in module` ... or something like that.. I think the current approach is not bad...
