Some of the `frand_range` calls were used for integer calculations, so we can use `Random::next` now.
This also reduces the number of C-style casts in the codebase.
Also includes support for more than two mainhall resolutions, zooming
so one mainhall can adapt to multiple resolutions, setting new mainhall
fonts, help overlays for all resolutions and adjustable tooltip padding.
Also allows preload screens to be any resolution & aspect ratio.
