Update Stanley to 2.3 and add scanignore

Stanley uses the `buildSrc` gradle folder, which generates class
files when running any gradle task, which caused some errors with the
scanner.

As the sources of those classes are all within the repository, they are
still open source and compliant with FDroid.
