AutoMerge Conflict Detector

AutoMerge Conflict Detector adds a button to the pull request view that exposes any conflicts resulting from automatic merging. Every time the button is pressed, the plugin performs a series of dry-run merges against the pull request target, master, and all upstream release branches. The number of conflicts and the conflicting file names are displayed in addition to a link to compare diffs.

Only branches fitting the "release/" naming convention will test automatic merge results. All other targets will be tested with a merge to itself and the default branch. Future configuration options to come!
