Yabfog Tools Update

I've updated Yabfog Tools for the OPML Editor.

It's a minor update to turn off the automatic re-installation of the new conversions since this is no longer necessary with the new updating procedure in the OPML Editor.

As of this version, no changes are made to your OPML Editor setup after installation of Yabfog Tools until you enable them in via the "Tools -> Yabfog Tools" submenu.
