open vipy in vertical split.

[MortalCatalyst]

How can I make vipy open in a vertical split by default?

Hey flebber; I actually haven't been developing vipy or using it for quite a while now. I am surprised you have it working at all!? I am unfortunately really busy this week, and since I am not using vipy myself these days it may be a bit before I can add new functionality if the vertical split isn't already an option. I would, however, be happy to accept pull requests.
