[Zope3-dev] Introduced a master check box to the ZMI

[Florian Lindner]

Hello,

Log message for revision 72287:
  Introduce a master checkbox to the ZMI that toggles all other check boxes 
from a folder listing.

I have checked in the change. I think the change itself is no problem and I 
hope it's done correctly. If not please improve me. If it's entirely 
unapprecated it will be also ok to revert it.

Regards,

Florian
