This is a tiny bugfixing release, fixing a few important issues. Most
importantly, copy/paste works again in the Tile Collision Editor, a feature
that broke in Tiled 1.2.1.
Changelog
Fixed cut/copy in Tile Collision Editor (#2075)
Fixed crash when trying to add Wang colors without a selected Wang set (#2083)
tBIN plugin: Fixed hang when locating missing tileset image (#2068)
CSV plugin: Fixed exporting of grouped tile layers
Many thanks to those who brought up these issues!
