Fixes #1 Support blame on files outside repo
Replaces blame regex parsing with more robust parser (also use s--incremental instead of --porcelain) Stops throwing on git blame errors (too many are common) Fixes issues with Diff with Previous command Fixes issues with blame explorer code lens -- with previous commits Fixes issues with compact blame annotations -- skips blank lines
