Paint Skins Overhaul

For offline use only. Complete overhaul of the vanilla skins (including awarded ones), which mainly removes or rearranges most of the nicknames/slogans, a bit like how things were before the console update. As well as replacing some skins with my own designs, but still trying to keep within the theme of Wreckfest. Thirdly, a few spoilers have been touched up with a bit of black spray. Note that some vehicles have been left untouched, like the Motorhome, either because they weren't playing ball, or I just like them as they are.
