Switch axes on the File Exporter

In each file exporter that Blender has, or at least the ones I used, which are DAE FBX, OBJ, ABC, I see the same problem: When the axes orientation in the exporter´s configuration is different than Blender's, instead of switching the axis, it applies some rotations, which is very annoying because, if you use it in an application like Unity, then you have a 90 degrees on the X rotation.

I think it shouldn´t be a big dead to fix that, and is very important.
