QtCreatorDeployment.txt currently requires and expects relative paths for source files.

I've got a file I'd like to deploy that does not reside within the source directory for which I could specify a full source path.

Currently when a full path is provided the source directory path is still prepended.

It would be nice if QtCreator would detect full source paths and omit prepending the source directory path in that case.

This would also be useful when deploying custom files that are generated in the binary tree during the build.
