Inclusive / Exclusive Filtering of Files in an Open Pull Request

Mostly need an Exclusive filter for Files in two scenarios

1)  Files that are essential for the project but not really reviewable entities in themselves as they are generated files ( like IDE project files ).  They generally just bloat the pull request

2)  Library Subrepositories that get committed as part of of a PR, but often are noise and have already been reviewed.    In these cases there's two kinds of filters needed  a) Filter out by a wild card path b) filter out a commit  ( as subrepositories are merged in with a commit, see https://github.com/ingydotnet/git-subrepo )

The ideal way to handle this is to be able to apply multiple filters, have standard filters per project and completely up to the reviewer what filters are applied ( with the option to always apple a default filter )
