Optimized smushed icons

I really like the icon design of the original icons.

When I tested today at http://gtmetrix.com/ i got this tip of loseless compress them. I run the ones I use at http://www.smushit.com/ysmush.it/ and it made some speed improvment of page loading.

Also I get this “The following image(s) are missing width and/or height attributes.” But I dont know if this is from theme or plugin,

Maby a tweak for coming versions.

Thanks again for the nice plugin!
