* UI/ChatBox: Use the new `defStyle` param for `RenderMarkup`

its color from the PushColor (since we're not doing actual tag stacks

* rebase touchup
* Implement showing rules on first connection
* Clean up RulesManager
* Change changelog and rules unread to use CVars
* Fix missing change
* Rename InfoWindow to RulesAndInfoWindow
* Change default server.id to unknown
* Fix invalid file contents and getting CVar
