Source map generation (script.js.map) (BZ#9207)

Source maps are useful for debugging production builds.

In our case, client-side warnings and errors are automatically reported to our server thanks to a custom qx.log.appender. These reports contain qx.core.Environment information and stack traces; they are the most important tool we have to resolve post-release errors and improve overall quality. Since the stack traces have references to the minified JS, a source map will help us pinpoint the exact location of reported errors.

I am adding some pointers in case a QX developer decides to work on this:

Makes sense.

I think this can be closed because the generator will be deprecated in qx6.0 and not further developed.
