Obscuring Names

[adya]

Rework Obscuring Names to make more sense.

• ~Instead of enabling obscuring by default unless excluded with NNDKnown this feature should be disabled by default unless included with NNDObscured.~ see comment.
• Name should be revealed as soon as NPC is activated

Algorithm for obscurity:

1. If definition for obscuring names present - use it
2. If not present (or names wasn't picked) check title
3. If custom title is provided - use it
4. If no custom title and isTitleless = false - use preferred obscuring name (originalName or ???. Original name is default option when not titleless)

Almost done. Need to test definitions and how it interacts with titles.

NNDObscured is no longer needed since NND can precisely identify all NPCs whose name can be determined. As such NNDKnown makes more sense as it can exclude NPCs who should be known from the start.
