Basecamp issue tracker integration
Description
There's probably a lot of issue trackers, but last time I fully moved to Basecamp, and heard a lot from others about it
From the version 3 (current) they have an OAuth and fully usable API
Proposal
Add an integration of Basecamp to service templates as another issue / bug tracker?
