Merge pull request #15 from matt2000/master

add instructions for immediate effect.
Wrap long lines of readme at 78 columns
Update copyright year
Update code blocks, enabling syntax highlighting
Move link definitions in readme to where they're used

Instead of keeping them all at the end of the document, making for lots
of scrolling if reading/editing the raw markdown.
Add updating section to readme
Change license to WTFPL (Do What The Fuck You Want To Public License)

Instead of using a slightly customized/stripped down variant of MIT,
let's use a standard license, that let's you do what the fuck you want
with the project. Like the customized MIT license's intent was.
