Use an eyedropper for color-picker icons
Summary:
The current icon is a black droplet which doesn't really communicate "pick a color from
the screen", though that's what this icon is used for. Other apps use an eyedropper for
this too.
This icon is a modification of one submitted in https://bugs.kde.org/show_bug.cgi?id=403924.
I've cleaned it up to pixel-align everything, use the correct margins, and do the CSS stylesheet
magic.
