Some more button polishing and change build install background to solid

[JohnAFernandez]

Change the background color on builds install screen and change classes of a few more buttons, especially in the mod details screen.

Heh I kinda liked the older style of having each build background visually separated, made it easier to hit the download button. Instead of red like it is currently, wait about just slightly lighter saturation of grey?

Well, when you hover over a row, it highlights, so it's still pretty easy to select the right button for each build.

Yeah that's at least helpful, too. If it's agreed that it looks better with these new changes, I'm all good :)
