Remove Bountysource links?

It seems that Bountysource has been shut down. Some months ago I tried to get a bounty for Feature: Built-in Tasker integration · Issue #257 · openhab/openhab-android · GitHub, but they didn’t pay me out and also didn’t answer my mails. Now the website isn’t reachable anymore. I guess we should remove all badges to this site, like I’ve done in the Android repo: Remove Bountysource badge (#3505) · openhab/openhab-android@7312e2f · GitHub


I opened PRs to remove the Bountysource badges from all repos.
