Fix cursor ghost at end of lines when cursor changes rows

Browse source 
WriteDeferredBuf now dirties the old cursor row before the render
loop so the reverse-video cursor block is erased.  FlipToScreen's
ghost cleanup was ineffective because FLastCursorRow was already
updated by WriteDeferredBuf.
