Explain how to set up WelcomeBot to run indefinitely

[brittag]

I'd like to run WelcomeBot in a channel I moderate, but I haven't run an IRC bot before, and I'm not sure how to set up a bot to run indefinitely/permanently. I'd like to see a bit of explanation for recommended ways to do this.

For example, my friend suggested that I could run it inside a screen session on the tiny server that I use for running irssi inside screen; I haven't tried setting this up yet though.

We've got a server for a bunch of openhatch stuff. I run WelcomeBot from there, using nohup to keep it from terminating when I log out.

Thanks for the issue! I'll think about how to add this to the documentation in a way that's general enough and specific enough to be useful. :)

I added a few lines to the README (one of the changes made here: cb2122e) -- do you think that's sufficient, @brittag?

To anyone testing this issue: follow the instructions here and let me know if you understand them, or if they need more clarification/don't work on your machine. You don't need to log into a separate server, you can test using your own machine and just see if you can close the terminal without stopping the program.
