Dev snapshot: Godot 2.1.5 beta 1
As Godot 3.0 is a major release with compatibility breakage, we are still going to support the previous 2.1 stable branch for some time. Many fixes and enhancements have been done in the 2.1 branch since the release of 2.1.4 in August 2017, so it's time to get them tested widely to go towards a 2.1.5 release.
