RFE: Horde Updates

Carrying over Horde update request from Bug #426, so that bug could be closed. Per Jamie's response on June 25, 2006:

You're right, Horde 3.1.x has now become the stable branch, even though there are still maintaining 3.0.x. I will add an installer for it in future, once I add code to handle its new configuration file format and install method.

Here are the current updates:

Horde 3.0.10 -> 3.1.2
IMP H3 4.0.4 -> 4.1.2
Turba H3 2.0.5 -> 2.1.1
Ingo H3 1.0.2 -> 1.1.1
Kronolith H3 2.0.6 -> 2.1.2
Nag H3 2.0.4 -> 2.1.1
Mnemo H3 2.0.3 -> 2.1

Please also adding the following new and missing Horde packages:

MIMP H3 (1.0)
Chora H3 (2.0.1)
Passwd H3 (3.0)
Forwards H3 (3.0)
Vacation H3 (3.0)

Thanks!
