Link to new Raphael-boilerplate repo (load raphael globally, with AMD, or HTML5 boilerplate.)

Build Raphael as a compatible anonymous module for AMD using Grunt

Use a custom build task in grunt to build raphael in a way that creates a valid anonymous module for AMD definition.

- Also pulls in the version from package.json to create the banner from copy.js (so the version can be set in one place)
- Conforms Gruntfile to most common tabs and spacing of other files
- grunt-cli should not be included in devDependencies (it is only ever installed globally)

Added to the documentation of the un* functions the #optional keyword.

Possibility to unbind all event handlers at once

Tiny bug, using 'Raphael' instead of 'R'

Line spacing added to Paper.print

Updating touch test for mobile devices

 Fix gh-407: added recommended UMD syntax to raphael for AMD support.
