tracks: Make the keyboard cursor more visible

The former grey was almost indistinguishable from its background colours
even on a good screen.  I've separated the cursor colour from the grid
colour and made it a lot darker. This gives a contrast ratio over 3.0
even against a darkened tile.

The cursor is still hard to see against trackwork, so maybe something
that isn't grey would be even better.
