PR merge policy

Require review? What if nobody reviews?

[rmanoka]

Expectation. Georust repos. should be constantly evolving: either add useful functionalities, or bugfixes; while also remaining a high-quality code base, and staying aligned to the short term or long term "agenda" declared for the repo.

With the above, I think an approving review from one of the "core maintainers / reviewers" is a must for PRs. The unfortunate side-effect — unresponsiveness to some issues / PRs — is a problem that plagues pretty much all open source repositories. Given the volunteer driven nature of the repos., I can't think of a good soln. for it. Just stating the obvious.
