Radio buttons and checkboxes are only properly themed in WebKit

Gecko (FF, SeaMonkey) is a lost cause for now, but Presto (Opera) could potentially be improved. Also need to look into what is possible in IE10.

Why not a (fallback) solution using a full sprite? That would require a JS addition but also replicate the holo design better.

I suppose a JS fallback is a possibility, but I kind of wanted to keep this pure CSS. I will definitely look into what is possible in Trident 6 (IE10) and Presto.

IE10 support was greatly improved in c83bf4b.
