Add option for strict parameter matching

[fczbkk]

There should be an option to set strict param matching. For example I want a pettern that will match ?aaa=bbb but not ?aaa=bbb&ccc=ddd. The loose param mathcing should be the default option, because that's what you want in most cases. But there should be a way to switch. Like this:

var loose_matcher = new UrlMatch('*://*/*?aaa=bbb');
var strict_matcher = new UrlMatch('*://*/*?aaa=bbb', {strict_param_matching: true});

var simple_url = 'http://inlinemanual.com/?aaa=bbb';
loose_matcher.test(simple_url);  // true
strict_matcher.test(simple_url);  // true

var complex_url = 'http://inlinemanual.com/?aaa=bbb&ccc=ddd';
loose_matcher.test(complex_url);  // true
strict_matcher.test(complex_url);  // false

Then we can add a simple switch (e.g. ?!) to the pattern, that will allow this:

// this...
new UrlMatch('*://*/*?aaa=bbb', {strict_param_matching: true});
// ...should be identical to this
new UrlMatch('*://*/*?!aaa=bbb');
