## Setup
* Setup as part of decorate when bounty system is enabled
  * Several bounty board locations with a WarriorGuard spawner in front of the board. Guard spawns and idles around 5 range.

## Tests

### ReportBountyMurdererGump
* Follows same behaviour as ReportMurdererGump
* Extracted common logic
* Didn't use staticgump due to several dynamic parts including input
* Optional bounty with validation >0 and <bankbox.total
* Murder report is honored either way

### Bounty boards
* Open bounty board with many bounties, no bounties
* Keep a bounty board open, invalidate a bounty by turning in the head, then try to click on the post of the now invalid post. As expected: does nothing
* Bounty messages use the last murder time as their post date and expire in 14 days
* Bounty boards/messages are not reliant on serialization; they use serialized fields from MurderContext to build messages when clicked.
* Bounty messages use synthetic serials so they do not have to persist bounty messages as items. They are constructed and sent as raw packets when needed.
* Players only appear on the bounty board if they are a murderer (though a non-murderer can technically still have a bounty if they decayed kills)
* Tested skin/hair color descriptions vs a dozen spot checks

### Head turn in behaviour
* Guard accepts head
  * Bounty -> gives bounty
  * No bounty -> generic response
  * Expired head (24h) -> generic response

NOTE: CUO "latest" has a bug with bounty/bulletinmessages that causes overflow outside of the container. It has nothing to do with this PR. It is fixed here in CUO https://github.com/ClassicUO/ClassicUO/pull/1871

# Murderer title

Bounty system and "murderer" title eliminated in [pub16](https://uo.com/wiki/ultima-online-wiki/technical/previous-publishes/2002-2/publish-16-part-2-5-23rd-july/). So UO:LBR and before had bounties and murderer title.

# Pre-T2A caveat

There were differences in pre-T2A, but this cannot be currently implemented because we do not have any pre-T2A systems in general, so at least for now, behavior is consistent with later eras. Pre-T2A was a whole other ballgame, but the bounty system still worked similarly.
