PSD cleanup

[laserlemon]

I noticed while working on #20 that the PSD could use some improvements that might make it easier going forward to transition Shields into a service (which I'm interested in helping with, by the way).

It might be helpful to convert shadows, gradients and color overlays to all use "Normal" blending. This makes it easier for something like ImageMagick or even CSS to build badges from composite layers. And these badges are sufficiently simple where that's entirely possible.

Also, the gradient in the PSD extends well outside of the bounds of the badge mask. That's fine for exporting badges but it would be nice to have the point-to-point gradient more strictly defined, again for ease in composition with ImageMagick and/or CSS.

I have a better idea. What if we scrap PSD files altogether. This is about to get a little ranty…

Why (the fuck) should I have to buy a $699 piece of proprietary shitware (that writes proprietary files) to hack on an open source project?

I’d propose that we delete shields.psd and stick with SVG and PNG images.

I’d also propose that we remove Illustrator noise from the SVGs and make sure they can be converted to PNGs using open source tools like svg2png or convert.

I’d be happy to submit a pull request that deletes shields.psd that closes this issue.

@sferik's definition of a "Cleanup":

I say do it! We have reference PNGs at this point, it's fine.
