version library for Haxe

Haxe macros useful for including version strings (version from haxelib.json, git commit hash and Haxe version) to a target build.

To use it, just install it via haxelib install version and use the -lib version switch for haxe.

Refer to Version.hx to see which macros are available and how to use them.

Credits for the idea go to Andy Li who presented a similar macro using git describe --tags in Haxe, a language that compiles to JS.
