//read url query string using mootools
/*
Function: $get
This function provides access to the "get" variable scope + the element anchor

Version: 1.3 (c)webfreak.no

Arguments:
key - string; optional; the parameter key to search for in the url’s query string (can also be “#" for the element anchor)
url - url; optional; the url to check for “key" in, location.href is default

Example:
>$get("foo","http://example.com/?foo=bar"); //returns “bar"
>$get("foo"); //returns the value of the “foo" variable if it’s present in the current url(location.href)
>$get("#","http://example.com/#moo"); //returns “moo"
>$get("#"); //returns the element anchor if any, but from the current url (location.href)
>$get(,"http://example.com/?foo=bar&bar=foo"); //returns {foo:’bar’,bar:’foo’}
>$get(,"http://example.com/?foo=bar&bar=foo#moo"); //returns {foo:’bar’,bar:’foo’,hash:’moo’}
>$get(); //returns same as above, but from the current url (location.href)
>$get("?"); //returns the query string (without ? and element anchor) from the current url (location.href)
