NewUI graphics for the cpanel

Remade the cpanel to be more in concert with the looks of the NewUI and to obscure less from the view. (and to remove the physicality of a dashboard)
I left in a fully transparent cpanel.png, mostly as a size template if somebody wants to work on it in the future or for a mod. (and I'll prepare my working Inkscape file to be able to easily batch-export, and upload it to the asset repo)
All graphics are slightly transparent.
All of them are double sized relative to the old elements, so it won't get pixelated on higher resolutions (tested on 1920x1080). This sadly also means that at lower resolutions, the small F1 etc texts on the button corners might turn illegible.
Hyperspace icon is a wormhole now, and the landing gear icon lights up when gear is down to provide more contrast. Alert statuses are differently colored with high contrast and [!] [!!] [!!!] to provide non-color difference too.
Most of the icons are from the same WPZOOM set the NewUI uses, and I tried to be consistent with them where I was needed to create new icons.
Some texts, like autopilot status might extend over the icons, but that was true for the old cpanel too.
The scanner doesn't have any graphics behind it. At first I put a semi-transparent gray ellipse under it, but it looked very odd when you didn't had scanner.
The time control buttons for the orbital map have a 1px gap among them, but that's because of their placement, not the images.

@dvolk: Most of these can be used without modification if you decide to work on the nonscaling flight UI we were talking about and I mocked up. Although most of them would need some scaling down to 80% (the F keys).
