 *	The script editor dialog.
 *
 * $Log: not supported by cvs2svn $
 * 
 * 15    10/08/98 4:24p Kevin
 * Changed code to comply with memory library usage. Always use mem_malloc
 * , mem_free and mem_strdup
 * 
 * 14    9/25/97 5:28p Samir
 * Even newer script code due to more changes in ObjCScript.cpp
 * 
 * 13    9/04/97 4:39p Matt
 * Added includes needed as a result of removing includes from d3edit.h
 * 
 * 12    9/02/97 3:28p Matt
 * Got rid of warnings
 * 
 * 11    8/29/97 2:21p Samir
 * Add some rich edit functionality.
