Allow for regular contributors to get away with 'infractions'

[orta]

For modules which aren't too popular, and for users who have submitted a lot of PRs (like 20-30+) we could

• Allow with no tests
• Allow other reviewers
• Allow PRs which touch tsconfig or tslint for that project

We could say only allow 1 of these at a time per PR, and to give at least a day before self merging is allowed.

I went over all of these, and I don't think that there's anything else needed beyond adding code to ignore config file changes that are OK.

Yeah, we don't need this anymore
