display more interface stuff, gave 2 walls colors, moved lights

in interface, gave things CONSTANTS instead of numbers - makes it much
easier to move UI around when you do parts in relation to one another
gave walls teal and orange colors
moved lights to have wall colors display properly
tried and failed to change the floor color (probably because it is a
terrain, not plane…?
added more comments and moved some variables around
display popularity (with customer satisfaction and hype) - but not yet
in meter form
moved advertisement menu
menu pops out from side of ad button, rather than under it
