Load Mozilla cookies.sqlite

The old-fashioned Netscape cookies.txt is nowhere to be seen in modern browsers. We should really move on to a modern format (e.g. Mozilla's SQLite-based cookies), so there will be no need for one to manually export cookies.txt anymore.

Also, this will allow for easier downloads of Bilibili's member-only videos, just grab a cookie file from your Firefox:

$ you-get -i -c ~/.mozilla/firefox/gggfz9xl.default/cookies.sqlite \

Bilibili uses CAPTCHA verification as part of its login process, so there is no way to automatize this like we do in Niconico. Preloading existed cookies is a must in such occasions.

The plan is to support the old plaintext cookies.txt, Mozilla cookies.splite and Chrome Default/Cookies. I'm not merging this til we're fully done.

Implementing Chromium cookies is non-trivial job - the encrypted_value stored in SQLite was encrypted using AES (therefore we need a 3rd party crypto library like pycrypto to handle the algorithmic thing).

Even more sophisticated, based on this article http://n8henrie.com/2013/11/use-chromes-cookies-for-easier-downloading-with-python-requests/, the encryption methods differ on Linux and OS X (didn't mention Windows).

Forget about Chrome, fair enough to support moz_cookies and cookies.txt only.
(To my knowledge, not only Firefox, but also some WebKit based browsers such as GNOME Web, makes use of moz_cookies too)
