w32_common: prevent display power management
Handling SC_MONITORPOWER doesn't seem to prevent the screen from dimming. The recommended way to do this in Windows XP and Vista is to call SetThreadExecutionState with ES_DISPLAY_REQUIRED. Windows 7 also has the PowerCreateRequest/PowerSetRequest/PowerClearRequest APIs but they're probably too complicated for this task.
