Replaced PyQuery with BeautifulSoup4 and lxml.

Should properly parse UTF-8 now.
Added some options (See readme).
Should produce (mostly) valid HTML5, when --replace-all=yes.

Should solve #51, #43, #39
Adds alternative for #41

Needed the changes for a project, and thought I'd share.

Code contains some more TODO:s.

supersede this by replacing docopt with argparse (more control?).

Unicode support should work properly now, including rss links.
Added a proper switch and CLI is more forgiving now (courtesy of argparse).

Would appreciate if someone would look at the commented lxml code and get it working, since currently the code runs BeautifulSoup twice.

Also, needs testing with git (I only need to generate a local copy without gh).
