Add wait point for entering manual normalization metadata

refs #5216

Add a 'user choice' after handling manually normalized files, so the system
pauses until manual normalization event detail information has been
entered. Since this is not a real choice, use set replacement dict with no
real value in replacement dict.
Add preconfigured choice to skip entering manual normalization metadata

refs #5216

Add 'skip waiting to allow manual normalization of metadata entry' to
preconfigured choices, and set the default to yes (skip waiting).
