Hi,

I needed a way to preprocess the script files before they were compiled, but after all the preprocessor directives have been processed in the script builder addon, so I have added a new callback for this purpose. I also use it to produce a preprocessed version of a script that includes many files, so that it can be distributed as a single file.

Please find attached the patch for the add-on. It would be nice if the modification could be added to the main branch - if you find it useful. I have tried to keep the semantics of the include callback (that replaces the default behavior).

Thanks for taking the time to check it out. My initial idea was indeed to preprocess with the callback before actually processing the files, but I tried to stick to the same semantics as the include callback, that actually replaces the include logic. So it's the same here, it replaces the processing logic, so that you can do your preprocessing and then call the compiler from there (it can be interesting to proceed this way if pre-processing is rather complex and requires that you compile several sections for example).

Thanks! :)
