==Why this patch?==
All my .mm files are version controled using CVS/SVN. What FreeMind has scratched my personal itch:
*Some attributes of FreeMind's .mm file are not suitable for version control.
*e.g., 'FOLDED' attribute saved in .mm file, makes documents changed frequently and unnecessarily.

==Overview==
*Save extra attributes into another file, named *.mmx
*defined three attlist.
**attributes listed in WhiteAttlist are the only attributes should be saved to files.
**attributes listed in BlackAttlist are the attributes shouldn't be saved to files.
**attributes listed in EmAttlist will be list in a single line. (a kind of EMphasis)

Attributes saved in .mmx file will be loaded when .mm file is open. Please see another patch:
*[[User:Jiangxin/Patch_load_mm_file_with_mmx_file]]
