test case illustrating updown control deficiency.

[C. Scott Ananian]

ChangeLog:
  - started a unit test case for the updown control
  - added a simple test illustrating a difference in wine/windows behavior.

This is a difference I found while porting 'sd' to winelib (this is in the 
Wine applications database).
