IE Browser support ? about mason

[RaphaelDDL]

I just debugged and found the problems:

• 1. Our friend Drew left some trailing commas on his main.js, so that causes errors on IE8 and below. Get http://masonjs.com/js/main.js contents and paste the code on http://trailingcomma.com/ so you can see the errors;
• 2. His demo page uses HTML5 elements, which of course fails on IE8 and below. Just include HTML5shiv or Modernizr (which is bundled with html5shiv) and all done, works even on IE7.

I just tested on older IEs (9,8,7) with IE10 dev tools, that is, not guaranteed the exact behavior of a real one, but at least console stopped crying with all these errors.

Hey @RaphaelDDL thanks for bringing that up. Good catch! I have updated the file.

@dreamzsiva - Raphael is correct on using modernizr to enable fallbacks for old versions of IE. I've gone as far back as IE8 for tested support.

@DrewDahlman checking http://masonjs.com/js/main.js again, still have one on promoted :P
