Add className property
V1.44.20131125: Fixed regression where flakeBottom would result in snow not properly sticking. Percent-based left/right positioning is now applied in all browsers, making resizing better.
snowStorm.usePixelPosition option to revert to px for left/top, in cases where body { position: relative } would break %-based positioning. Attempt to get computed style and use pixels automatically. Fixes issue #14.
targetElement examples, relative and absolutely positioned w/overflow:hidden
document.body || document.documentElement, as documentElement failed in IE 6. Probably safe to remove. Correct positioning and use pixels when targetElement is specified, should fix issue #13.
