Description

Pass each non-empty line of post-processing script through the placeholder token parser. Many post processing scripts are unaware of the environment variables that are set, and instead provide parameters that should be set to those values. This change lets you use slicer variables with those scripts as written, to help eliminate crashes and other errors caused by mismatched parameters.

Uses the existing placeholder parser used by the filename format setting
Tooltip and wiki updated
