[FREELDR:UI] Improve menu timeout drawing.
Fixes CORE-13827, where the timer countdown would otherwise display incorrectly if there were no trailing spaces after the timer string. Now, the countdown is always appended with one space separator after the end of the string, **or**, it is inserted at a specific place delimited by a %d insertion point in the string. Also, don't repaint the date & time (in full-UI mode) many times per second -- instead of only once per second -- while displaying a menu.
