Player progress drawing rewrite (both emptying cup and full-line bar): * Fixes FS #6820, related to the glitch that progress moved in the opposite direction when seeking. * Smaller, more efficient code. * Full-line bar only displays as many software defined characters as needed, freeing the remaining ones for other text. * Don't cut last digit from times >=1 hour (at the cost of inexact last progress bar character).
