python-colorama breaks jedi-vim plugin on xenial

[Dan Watkins]

When the jedi-vim plugin runs colorama.init(), colorama assumes that the vim.message object which is sys.stdout (and/or sys.stderr) will have a 'closed' attribute. It doesn't which causes the following traceback:

Traceback (most recent call last):

I uploaded 0.3.7-1 to Debian. As soon as Launchpad picks that up, I'll syncpackage it back to Ubuntu.
