Due some problems with reading the input file or similar I will reduce the double checks for these WUs with error "Missing or invalid NewPGen header, next data lines will be flushed..." The new validator should flag these units as invalid.

After a bugfix in substring validator code its working now. The validator for Sierpinski / Riesel base short was replaced.

validator version status by app:

Sierpinski / Riesel Base = new
Riesel Base = new
Sierpinski Base = new
Sierpinski / Riesel Base - short = new
Sierpinski / Riesel Base - long = new
Sierpinski / Riesel Base - average = new
Riesel Base - short = new
Sierpinski Base - short = new
