Release Name: 1.4.5

Notes:
* Undid the change in 1.4.4


Changes:
* Reverted the change in 1.4.4. We need unsigned longs in a few cases.
  Consequently, you should upgrade windows-pr to 1.0.8 or later because
  some return values were set to -1 instead of 0xFFFFFFFF as they are now.
* Updated one test to validate return value from failed function.
