[sork] vacation + horde v3

[Bas Beenhakker]

Hello,

Untill searching the mailing lists, I didn't know or saw that the vacation
module was only supported by horde v2.x.

Pity, because I had just made adjustments to be able to use different 
drivers
for different backends. I couldn't test it - so installed a clean 
vacation version.
Still nothing.

I think there should be a notice on the Horde/vacation site about this fact.
This will save a lot of hassle for other Horde users.

Kind regards,

Bas Beenhakker
