Use --online migrate if container is running

[GoogleCodeExporter]

Reason:
Stopping a running container to do a migration is inconvenient.

Description:
I'm sure there's a cleaner way to do this in Ruby (I'm more of a Python coder), 
but here's my patch for  app/models/virtual_server.rb to handle online 
migrations if a container is running.

Yet better is to have a way to choose between live and offline migration.
