Title: Script Encoding Exe Default to exe-small

When encoding the exe in script files to write to the disk the filesize of the script is often rather large due to the way we have to encode the buffer.

For example vbs with the standard exe is 609759 bytes but with exe-small it drops to 38471 which is a large difference.
