Extension of ModelCHECK to check regeneration status

[DomenicLaritz]

To increase the overall model quality, we would like to prevent incompletely regenerated models (traffic light status is yellow) from being checked in to Windchill.

Therefore it would be very helpful if there were a ModelCHECK check (see also PTC article CS39546).

As of today, only the config.pro setting "regen_solid_before_save prompt" can be used to inform users about incompletely regenerated models when saving.

However, since we also use the config.pro setting "dm_auto_conflict_resolution yes" to suppress annoying and superfluous conflict messages from Windchill, the setting "regen_solid_before_save prompt" does not work for us either, since this message is also suppressed.

@lwestbrook, I consider this requirement to be a low-hanging fruit that would be easy to harvest:
If the toolkit function ProSolidRegenerationstatusGet() results in the status PRO_SOLID_NEEDS_REGENERATION, that results in a ModelCHECK error, otherwise it doesn't.

@DomenicLaritz Thank you for adding these details. It is certainly something we want to implement, but unfortunately, I don't have a timeline for it at the moment.
