[evolution-patches] fix for #313096 (mail)

[Vivek Jain <jvivek novell com>]

Hi,

The attached patch fixes
http://bugzilla.gnome.org/show_bug.cgi?id=313096 .

We don't want to load multiple plugins at all on this hook. As IMHO
having multiple junk filtering mechanisms simultaneously is not a good
case, so we disallow that. 
This fix stops hook to load a plugin if it is disabled.
So you just have to disable the unwanted plugin, to make a non-default
plugin work.

Thanks,
Vivek Jain
