ENOENT neko error on windows

[nulld]

This error occures when trying to exec haxelib run nme for e.g. It tries to execute run.n neko script and fails.
Same thing with main : Foo.hx in haxelib.json but looks like ENOENT haxe.

After some investigation found that nodejs spawn ignores PATHEXT on windows.
nodejs/node-v0.x-archive#2318

Changing neko to neko.cmd there https://github.com/lix-pm/haxeshim/blob/master/src/haxeshim/HaxelibCli.hx#L89 fixes this issue.

There are wrapperlike solutions via it can be fixed crossplatform. How about using something like this one, instead spawn?

I think it is fine to add dependencies as we are already using an augmented version of fs: https://github.com/lix-pm/lix.client/blob/d026272935ac1d26d72d3b80f0f0e14222b445a5/package.json#L22
