Further prepare for color rendering; highlight row and column
Now palettes are allocated and deallocated in fteapot as well as teapot; both executables have some color rendering, with fteapot using the cell foreground and background (there's just no way to set them at the moment). teapot is so far only using color in the header. Implements #39.
