haxelib version outdated

[wiggin77]

Any chance you can update haxelib with the latest? Currently someone trying out the haxelib version will trip over the Helper.isValidElement issue (fixed here) and a bug parsing TiledObjectGroups (also fixed here).

Cheers!

@kasoki Please. I'm currently relying on the git versions of this package and openfl-tiled-flixel. I'd really like to have the haxelib ones updated.
