Crop Feature

[Davidhoechtl]

I ran into the problem that i need to crop all the layers before export.
Currently each layer (also hidden ones) are getting exportet in the resolution of the original sprite.

In my case i want the script to do a crop before exporting each layer, so there are no empty spaces around the png.

Thank you for your work and i m looking forward to see that feature :)

Pardon me. I ment Trimming the excess space

Me again. I opened a pull request where i successfully implemented the requested feature. Tested with scale 1 and it worked perfectly.

(This is actually my first contribution to an opensource project.. feels good :-))
