Drag and Drop support added in layers panel!

I'm still working on creating a better work flow for you .. just added drag n' drop to the layers panel.

This is what you can do:

1. Drag the layers to sort them. Unlock the background to be able to move it.
2. Drag a layer to the trash to delete it.
3. Drag a layer to the New Layer icon to duplicate it.

I'm quite satisfied with it, ie it works as i should :) What do you think?

Peace!
