Add support for placeholders in display names in different contexts

[adya]

With recent release of wSkeever's mod it is now apparent that any further useful dynamic additions to the name is not possible.

To mitigate this NND should be able to:

1. Substitute placeholders in any context.
2. Add support for several placeholders:
   2.1 [race] - race
   2.2 [sex] - sex
   2.3 [relation] - relationship disposition
   2.4 [class] - class or combat style (e.g. warrior, mage)
   2.5 [carry] - show carry weight
   2.6 [break] - new line

Take into account unique names that were previously bypassing any modifications.
Maybe support for obscurity names too?

Nah, this one is not that crucial, so will postponse until requested.

Keep in mind that some info that might change in runtime will significantly complicate name fetching as it will require continuous updates.
