Removed $.browser to support jQuery 1.9

[joshlangner]

jQuery 1.9 removes $.browser. Some limited testing (IE 7-10, Safari 5, 6, Chrome 24, Firefox 18) suggests that this should be enough.

are you sure this is a valid fix? now the code is always run when !supports_onhashchange is true whereas before it was only run when executed in IE.

Its only checking for IE that is missing, right, so how about changing that code to:

(navigator.userAgent.match(/MSIE/i) !== null)

?

I sent a pull onto your fork, if you want to add that to this pull.

What about IE9 and IE10? Will they handled properly?
