Add a %marriage_is_married_chat_prefix% placeholder.

[slash1div]

I've been unable to tell if someone is married via in-game chat due to how my chat management plugin works. Adding a placeholder for the marriage status chat prefix would save people who use plugins like Chatcontrol that wipe the prefix.

The right repository for this is https://github.com/lenis0012/papi-placeholder-marriage

But yes, this will be added very soon to the ecloud expansion.
