Badge request: OpenHub

:clipboard: **Description**

Please provide badges for OpenHub, because the provided badges from OpenHub do not fit among other badges (from Shields.io) in README files.

Open Hub is a statistics website, that scans registered open source projects e.g. on GitHub and creates global statistics per user and project. E.g. it aggregates all commits a person has ever done in any repository. It indexes 495k repositories and counts 4.9 million contributors.

:microphone: **Motivation**

* The provided badges from OpenHub do not fit among other badges in README files.
* FOSS contributors might want to publish their aggregated statistics gathered from multiple repositories and repository platforms on personal websites or profile sites.

Start with the OpenHub API documentation at github.com/blackducksoftware/ohloh_api#ohloh-api-documentation and review the related UI resources linked in the issue. Confirm which user or project metrics and API access requirements are in scope; the work is done when the agreed OpenHub badges produce consistent Shields.io output with real data.
