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
The we could keep the current approach :) the thing is that in my case it compares ["a string \n"] with "a string".... i could also use a line line `if exclude_file.find(module) == -1:` but in my opinion the -1 is not that readable...
