FeatureSummary: Improvements to the `DESCRIPTION` handling
- The
feature_summarycommand in theFeatureSummarymodule accepts the newDEFAULT_DESCRIPTIONoption that will print the default title for the selected package type. - The global property
FeatureSummary_<TYPE>_DESCRIPTIONcan be defined for each<TYPE>to replace the type name with the specified string whenever the package type is used in an output string by theFeatureSummarymodule.
