[Compiler] Output all scripts as text.

[ZoriaRPG]

I've suggested this to Saffith in the past: A compiler option to append, and save all scripts (the buffer, plus imports) to one text file, would be nice for handling quest script distribution.

I am OK with this feature so long as it can generate comments at the top of each file explaining what file is about to begin.
