This patch remove remoteDebuggingPort option. Instead, browser is launched with '--remote-debugging-port=0' flag, letting browser to pick any port. The puppeteer reads the port number from the browser's stderr stream. This change cuts average browser start time from 300ms to 250ms on my machine. This happens since puppeteer doesn't have to probe network once every 100ms, waiting for the remote debugging server to instantiate. Fixes #21.
