	Property: set
		Sets a cookie in the browser.

	Arguments:
		key - the key (name) for the cookie
		value - the value to set, cannot contain semicolons
		options - an object representing the Cookie options. See Options below. Default values are stored in Cookie.options.

	Options:
		domain - the domain the Cookie belongs to. If you want to share the cookie with pages located on a different domain, you have to set this value. Defaults to the current domain.
		path - the path the Cookie belongs to. If you want to share the cookie with pages located in a different path, you have to set this value, for example to "/" to share the cookie with all pages on the domain. Defaults to the current path.
		duration - the duration of the Cookie before it expires, in days.
					If set to false or 0, the cookie will be a session cookie that expires when the browser is closed. This is default.
		secure - Stored cookie information can be accessed only from a secure environment.

	Returns:
		An object with the options, the key and the value. You can give it as first parameter to Cookie.remove.

	Example:
		>Cookie.set('username', 'Harald'); // session cookie (duration is false), or ...
		>Cookie.set('username', 'JackBauer', {duration: 1}); // save this for 1 day
