//	AUTHOR:		Ingo Clemens
//	DATE:		July 09, 2004
//
//	DESCRIPTION:	Saves the scene file with an increasing version number. If the file has
//			no version number to begin with, it's added to the name.
//			In addition to just simply save with an increasing version number, the
//			user gets prompted to enter a file description of the last scene file,
//			which then gets written into a texfile that lies within the scene directory.
//			Good for keeping track of changes within different scene versions.
//
//	VERSIONS:
//			1.3 - Oct 24, 2005
//			- made the script save the scene also in subdirectories
//			- file names are checked to prevent overwriting
//			- removed all global variables
//			1.2 - Aug 21, 2005
//			- changed the counting policy for as the file name must not contain an
//			underscore anymore
//			1.1 - Jul 29, 2005
//			- made the global variables more unique by their names
//
//			1.0 - Jul 09, 2004
