[USETUP] Progress-bar: minor improvements.

Browse source 
- Simplify the usage of the PUPDATE_PROGRESS callback.

- Add the possibility of specifying an initial non-zero StepCount when
  creating the progress-bar (using the -Ex version), so that it can be
  initially drawn with the expected initial count.
  Of course ProgressSetStepCount() can continue to be used.
