Add The Option to Mark Survivors/Killers as Favorites.

This is a feature that becomes more desirable as the roster continues to expand. Having the option to mark a character as a favorite would be a nice quality of life feature. I don't like having to scroll to choose my survivor, and there are times where I get a bit lost on the character select screen. Marking a character as a favorite should float that character to the top of the character select screen. Multiple characters per role can be marked as favorite and it would simply order the favorites by release order the same way the current system (almost) does.
