Add rails rainbow_pool:import task, to get clean image hashes for pets

Used to have something like this long ago, now here's the latest

This task can't run autonomously, it needs the human user to provide a
neologin cookie value. So, no cron for us! But we're cleaning up *years*
of lil guys in one swoop now :3
