Add "apply transform" to export options

[Peatral]

Added an option to the export options. When disabled (enabled by default) the transform does not get applied during export.

I found myself in a situation where this is quite helpful. When creating vehicles you often have to align positions with bones from the rig. Before exporting I always had to clear the location and reset it after, this solves this. (I have the complete model and moving its way easier to just keep the parts where they belong and don't apply the transform during export)

As it is enabled by default the current behaviour should not change as long as you don't touch the option.

I am open to modify this that you can toggle location, rotation and scale individually for those who need it.

Thanks for the pr! I should have time to give this a proper look over tonight

Looks good from a brief read, but I'll let Presto review it properly, one comment, in init, add your name to the authors list at the top :)

Ok I will add my name :)

I also added finer control over what should be applied and what not.

I actually prefer the original implementation with less control - one of the key ideas of the exporter is to limit the number of options people have to think about - would you mind changing back to the original? I think in general the desired behaviour will be to apply or to not apply, we can always adjust this later if need be

unless theres some logic for the workflow you can explain why you'd want only part of it?

[Peatral]

Ok, I will change it back. If it should be needed in the future we know where to find it :)
