small changes in response to pyflakes pass
Only significant change: removes incomplete kernelstarter file, which shouldn't have been in the repo at all.
closes#1499
ensures that config loading matches what would happen in ipcluster.
The only change needed in IPClusterStart itself was moving the on_stop registration from init_launchers to start_controller, where it should have been anyway.
This exposes ipcluster's over the web. The current implementation
uses IPClusterLauncher to run ipcluster in a separate process.
Here is the URL scheme we are using:
GET /clusters => list available clusters
GET /cluster/profile => list info for cluster with profile
POST /cluster/profile/start => start a cluster
POST /cluster/profile/stop => stop a cluster
