Not compatible with 4.7/4.8

[Jamus Jegier]

I'm getting a "This add-on is not compatible with your Bitbucket instance. Request an update from the vendor." message in Manage Add-ons with 4.8. I also see a review in the marketplace that asking about support for 4.7.

I updated our Bitbucket server and it seems that 4.0.1 is compatible with 4.7 and 4.8. I adjusted the compatibility settings accordingly.
