UI Overhaul

Has been tested pretty thoroughly, looks a lot less cluttered with a much more "appealing" (in my opinion) color scheme, using colors from aosp contact icon colors. This is the previous Navigation Drawer/UI Overhaul commit without the navigation drawer part. The changes are all xml (except for some changes to some color integers) so nothing should be broken, and after testing it, it seems like nothing is broken
