Did some more cleanup on here to get some more consistency.
Imported only the fonts we were actually using in here. There was a lot of legacy font weights and sizes we didn't call anywhere in the app anymore. Fonts are a huge overhead, and the less families and weights, the better.
Remapped the color palette to the Material UI conventions. The majority of the color palette was grayscale, so I mapped the colors we were using, to their closest values in the grey scaling.
Also, I imported most of the default material values into Theme.js, mostly to know what you have access to when coding in terms of color, breakpoints and font variants.
Removed "body1" variants off the Typography components, as that is the default variant, no need to declare it.
