tests.
- Removed a trace that shouldn't have been there.
- Add return checking to SPI_{GET,SET}WHEELSCROLLLINES and
  SPI_{GET,SET}MENUSHOWDELAY unit tests so they no longer run on
  Windows 95 where they aren't supported.
- Changed minimum hovertime in SPI_{GET,SET}MOUSEHOVERTIME to 10 as
  Windows XP defaults to 10 any value below that.
