Add switch for menu color

[MitchellSingleton]

As a user, I want the capability to select a higher contrast color scheme for the emulation station menus (preferably black or white text instead of grey on top of a light grey or dark grey background), So that i can more easily be able to see the menu items due to eyesight or hardware, Where as currently the color appears to be hardcoded.

the minimum is a switch to enable using black as the text color and white as the highlighted text color.

This change would increase the difference between the foreground and background colors.

a stretch would be custom configuration of the foreground, background, foreground-selected, background selected colors.

I'd like to add that with the menu in dark mode, the highlight color for the selected row/item is basically indistinguishable from the rest of the menu. The black "highlight" is almost the exact same color as the dark gray of the unselected rows.

Please add an option for higher contrast of the highlighted row/item in the dark mode menu.
