IE8 Support

[iotku]

While I'm not too enthusiastic about adding IE8 support, as far as I can tell there's only a few barriers keeping the timer from working under IE8.

One notable case is totalSplits generation via: Object.keys(splitsObject)

I assume everything should work in IE9 or greater, but I don't want to upgrade until I've tried to get this functional for the unfortunate souls still using IE8

#8 would also need to be fixed, most likely

I'm adding more stuff (SVG) that IE8 doesn't support without significant hacks. Might want to look into Modernizr a bit at some point but eh.
