Further comments

Basically 2 new features were added.

1. Highlighting by username: The users can provide a username. If a chatmessage has an author with that name it is highlighted. Since regex and case sensitivity don't really make sense for usernames I removes the options for those.
   
   Additionally a button was added to user cards to quickly toggle highlighting for the user.
   

2. Highlighting by badge: The user can select a badge from a list and all users with this badge have their messages highlighted.
   The list of badges is grabbed directly from twitch, so no manual changes have to be made when badges are added or removed.
   

For a future update it could make sense to also add a way to change priority of highlights (for cases where messages fit multiple highlighting settings). At the moment the highlight which was created last has the highest priority, regardless of which kind of highlight it is.
Another idea for teh future could be adding 3rd party badges to the list for highlighting.
