* Rename ChatSanitizationManager to ChatEmoteSanitizationManager
The prior name was kind of confusing as there's a emote one and
then now there's also chat expansion happening in the accent system,
so knowing which I actually need to edit is useful.
So, I just need to keep myself not confused.
* Rename smileyToEmote and remove punctuation duplicates
The name SmileyToEmote is just... Bad.
Plus, I needed to remove the punctuation duplicates as that would
break any kind of regex parsing that I tried.
* Switch to regex from checking end of string
I also changed from System.Globalization to ILocalizationManager.
Writing that regex was definitely an experience.
* Document regex and the manager
* Rename it back
* Simplify regex
