Title: ProGuard config files as vendored

ProGuard config files have a `.pro` extension. Thus there are detected by Linguist as QMake, Prolog or IDL.
These incorrect results can be seen here: https://github.com/search?q=extension%3Apro+proguard&ref=reposearch&utf8=%E2%9C%93
This pull request adds these files to the vendored files.
