Update 1.0.1.50

- Added more leaderboards. - Timer will now countdown when not playing. - Fixed start-button behaviour during PowerSpins. - Windows Volume mixer now linked to app. - Removed 'spins'. Now for a spin, 1 credit + (stake - 1) games are needed. At lowest stake, a credit will be moved to games when needed. - Removed thirdparty soundlib, now using DirectSound directly. - Reduced CPU usage (not by much since it was already very low).
