Project Replace should affect custom metadata, snapshots [#2985]

I spotted this in the latest list of fixes.

Should Project Replace really affect snapshots? Isn’t the point of them that they are a fixed record of a document at a particular time?

Or is this something the user can choose? If so, I hope the default setting is that snapshots are outside the scope of a Project Replace.

Previously it was on by default. Now it is off by default. In some cases this might be useful if you want to change globally the name of some character in your book.
