Command-line tool to manipulate time codes

Per Greg's suggestion, this is a command-line tool allowing one to quickly view, dump or replace time codes of a Slide Deck presentation. (This functionality will eventually be in the butter plugin, but that doesn't exist yet.) It uses Python with lxml. It alters whitespace, encodes non-ASCII entities and uses HTML-style self-closing tags, but doesn't otherwise mangle the original document.

Usage: ./times.py show slideshow.html
       ./times.py dump slideshow.html > times.json
       ./times.py write slideshow.html < times.json > modified.html

$ ./times.py show index.html

$ ./times.py dump index.html 
[1, 4, 9, 14, 17, 20, 22, 24, 27, 30, 33, 34, 35, 38, 42, 43, 44, 45, 46, 48, 49, 52, 53, 54, 55, 56, 58, 61, 62, 65, 67, 68, 73, 77, 78, 80, 82, 87, 89, 90]

For now this considers a "slide" to be any element with a popcorn-slideshow attribute instead of looking for the slide class, because I couldn't find a reliable way to precisely query classes with XPath 1.0 (used by lxml). If we're generating new presentations we'll need to specify a placeholder value or modify this.

I'm not sure where this file should go. Right now, everything in here seems to client/browser code. Maybe we need a /bin/ for tools?
