multiple version of python support

[living1069]

Is there any possibility that the plugin supports multiple versions of pythons?
I have used vim-R. It can use all the R versions.

Sorry to have been absent, thanks for trying out vim-ipython.

I'm going through old issues and it seems to me that it makes sense to close this one, as it is a duplicate of #39.

Thanks @living1069 and happy hacking!
