82 bitbucket

This patch also fixes this plugin. [It wasn't working](https://github.com/bugsnag/bugsnag-notification-plugins/commit/42531bf26dbbb4bf6db8fa57b6bceb03ee6049ac). Bitbucket issues can be "open" or "resolved", and they also have irrelevant statuses like "on hold", "wontfix", etc. The integration just sets an issue to "open".
