feature request: build cancellation callback

It would be useful to get a callback when a build was canceled. My use case is that I am making changes to project settings during pre-process depending on some conditions. I want to revert those changes once the build has finished, be it canceled or sucessful, so that the working copy is not altered by the build process.

I second this, I use build scripts to strip out certain Resources folders via an AssetDatabase.Move(), so not being able rename those folders when the build is canceled is just bad design. I'll have to write a editor script that looks for Resources folders with our special extra character and rename those as a user accessible editor tool to get around this.
