Subject: Cookie injection support
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Add command-line options injecting individual cookies or cookie file
into Chrome. Provide default cookie file.

This changes the IRC bot’s command splitting to shlex.split, which
allows shell-like argument quoting.

Fixes #7.
