[Feature] Include/Exclude timestamp on generated files


Ability to include or exclude the timestamp on generated files.

Suggested by @e36M3 here:
The ability to remove the timestamp from the generated classes, this is an issue if I choose to always regenerate my classes even though perhaps I only changed 1 or 2 classes. The problem is that source control thinks that all of them truly changed because of the timestamp and it checks in a new version every time for no good reason.
