Run MailCatcher in the background, always, on OS X

Place me.mailcatcher.plist into ~/Library/LaunchAgents, then run launchctl load ~/Library/LaunchAgents/me.mailcatcher.plist.

If you use pow, echo 1080 > ~/.pow/mailcatcher and go to http://mailcatcher.dev, otherwise use http://localhost:1080.

Currently pow doesn't seem to pass websockets through correctly. Looking into this.
