[Improvement] Filtered Messages Extension (#4435)

* [Improvment] Filtered Messages Extension

Added:
ItemSpeech 25
Strikethrough 26
Stuns 27
BardSongsOnPets 28

I wired up Strikethrough and Stuns as they already had message entries.

ItemSpeech and BardSongsOnPets do not appear to be currently used in the source.

Note: There are still 5 unknown Filters in RoF2 that need to be investigated:

Achievments
Fellowships
Mercenary Messages
PVP Messages
Spam

* Spelling Error

* Missed some stun calls
