[WIP] New Pixelation Icon Sets

[Indigo]

Definitely love the flavor of these icons.  Really great work.  Some of this is going to seem pretty nit-picky but, that's the nature of icons/UI.  One general critique that covers all the icons is you seem to have embraced angles far more than the philosophy of the theme itself.  The theme almost entirely about straight shapes - rectangles and boxes.  The only angle we use is 45, and we use it very sparingly as a top-left corner treatment and for cast-shadows.  Reducing how much you're using angles in these icons can help a lot towards making them feel more unified with the theme.  AA really shouldn't be necessary in these.

Here is a quick example of how to address some of the issues.

Implementing all of this, except for a few things:
The lock icon sizes are more consistent with the page icon sizes, seemed easier to recognize in the layout.
Kept the values of the icons so they work on the forum colors instead of 50% gray.

Here's one with the slant.

I'm not digging that slant. Could be the AA, but I'd ditch it.
