Coverage overlay for PRs

[jarekwg]

Related to #10,
But would be really awesome to have the overlay on the diff overview for PRs.
ie on this page https://github.com/<org>/<repo>/pull/<#pr>/files

The old codecov extension offered this and it was amazing. After submitting a PR, one could see which lines of the code they'd touched were covered.

It was especially nice how it'd continue to use a darker green/red highlighting in the line number gutter to indicate which lines were added/removed, whilst the lighter green/red highlighting across the actual code indicated what lines were covered by tests.

All the best. :)

This depends on sourcegraph/sourcegraph#911, I have a WIP prototype PR up at sourcegraph/sourcegraph#911

Where would I find docs on this? Videos in that blog are broken

As I understand this is now deprecated. Any plans on resurrecting this amazing overlay feature?
