Support preview for custom transforms in web.config

Currently we do not support preview for custom transforms in web.config. We should consider supporting this if possible.

upvote for this feature.

Also it seems that your using the transformtask by mocking the build engine

                <TransformXml Source="web.config"
                      Transform="web.dev.config"
                      Destination="$(TransformDest)" /> 

locally it seems to lock files. If your batching transforms (breaking xdt's by module) it will fail on the second xdt file.
