Support .appup.src[.script] files

Similar to how .app.src are being handled, all files in directory
.src ending with .appup.src are processed, checked for
correctness and copied to ebin without the .src extension.

By way of using rebar_config:consult_file/1, .appup.src.script
files are automatically supported in exactly the same manner
as in .app.src.script.
