Added a link to the live demo.

Hey there, GitHub Pages.
Turns out protocol-agnosticism isn't cool here.
Added rule compilation.

Grue parser rules now support a simple, named-parameter syntax, making
it possible to write some commands without regular expression syntax.
Updated the demo.
Removed redundant sanitization.
Add support for regions, easier rule definition.
Revised "look", centralized AMD testing.
Boolean bug.
