DESCRIPTION:
 Shelf Error Fix. 

Removes flags from maya shelf files for backward compatibility.
The shelf has items that cannot be read. The shelf will only 
display the items before the first unreadable item it finds. 
If you start Maya and save this shelf then you will lose the 
unreadable items. This will happen automatically if you have 
your preferences set to save the shelves on exit.

INSTALL:
 Quit Maya if it is running.
 Copy the script and icon files to the default maya scripts and icons folder.
 If you do not set the MAYA_APP_DIR variable, the default values are:
 Windows XP
  \Documents and Settings\<username>\My Documents\maya\scripts
  \Documents and Settings\<username>\My Documents\maya\<version>\prefs\icons
 Windows Vista and Windows 7

 Linux (64-bit)
