Add support for js.import(path, exportName)

[haxiomic]

For example:

@:js.import("three/examples/jsm/controls/OrbitControls.js") extern class OrbitControls {

does not work because it tries to import "three_examples_jsm_controls_orbitcontrols_OrbitControls", rather than just OrbitControls. Given the module could export under any name, we need a variant where we specify which import we want

Thanks! I'm merging this , because there's no reason why the user should not be allowed to customize the name (especially if it's something that's not a valid class name in Haxe).

Still, I think that maybe the primary problem with the current implementation is that it uses the fully qualified name. If it only used the class name it self, would that solve your particular issue?

Ty :)

In this case yeah using the haxe class name would solve the issue (but as you say, in general we need to be able to override this for non valid haxe names)
