Committing patch [#23278] (by me)

This patch allows a user to pass binary data to LibLoad() to load a blend file from memory instead of a file path. I don't know how useful this will be for others, but I've used it so far for:
  * Decrypting .blend files and loading them without having to store the .blend on the hard drive
  * Pulling .blend data out of an archive and loading it (again skipping the hard drive)

So, it seems the biggest use for this is skipping a bit of file IO (and possibly some security problems).

Example usage:
import bge

with f as open('myfile.blend', 'rb'):
    data = f.read()

bge.logic.LibLoad('Name', 'Scene', data)
