jp9000 58be029b14 UI: Fix twitch stream stat window not centering
Fixes an issue where if you auth to twitch, then close the program
without unhiding the twitch stream stats panel, the next time that panel
was unhidden it would be at position 0,0 on your screen.  This
explicitly sets its position to be center of the window beforehand to
ensure that won't occur.
