Makes IE8 + IE7 work

- new, clearer bind polyfill
- don't use ```location``` as a var name (I thought IE was getting tripped up on this. turns out it wasn't the problem, but its sort of a keyword, so I figured it's just as well to rename this)
- move back to jQuery 1.11 as 2.x doesn't support IE8-
- parse ints before creating date objects or IE (and Safari) will spit out a bunch of ```NaN``` when you try to access bits
