Title: Dragging still buggy with Opera 12.10. Also, support3d is always false.

Dragging is still buggy even after closing #160:

It works with Opera 12.00, but fails with 12.10, because the prefixed form of the css transform property is buggy in 12.10 (it is considered [deprecated (read more)](http://my.opera.com/ODIN/blog/opera-12-10-is-out#csssitecompat) since that version of Opera!). I implemented a more clever css-property prefix sniffer to solve this problem: It prefers the un-prefixed (=as per spec) version of the property, if supported. Also, it can be used for arbitrary css properties.

Also, support3d is always false in the current implementation. (Don't know what `support3d = iD.util.prefix() === "O"` was meant to do :confused: ). Replaced this with a proper feature detection for translate3d based on [gist#3794226](http://gist.github.com/3794226).
