Need DUB pull request reviewers

[Sönke Ludwig via Digitalmars-d]

We have a current shortage of reviewers for the DUB repository [1]. 
Martin is more or less the only one apart from me, but we are both 
currently too busy to get this done in a timely manner. If anyone can 
spare a few minutes (maybe even regularly), that could be a great help, 
even without specific knowledge of the code base.

Thanks,
Sönke
