This makes it much easier to work with a device where we don't expect a persistent commandline session. Prompt no longer actually makes a prompt but rather just runs an http server. This is just a v1 patch. It doesn't work with android yet and it isn't smart enough to allow you to run more than one copy of prompt.cc at the same time (since you can't control the port it listens on). If you have a second copy of prompt runnning (or anything else bound to port 7777) it will just crash. We could make this a lot better, including splitting out the pid-file tracking for sky_server into sky_server instead of having skydb manage it.
