message: doc: Update CHANGELOG to reflect logging changes
diff: ## API Changes
  +- Removed RequestLog/Log access in API, as those messages were deprecated in v2
  + of the message spec.
  + - Older apps will just receive an error when RequestLog is sent.
  - Creating a server now takes a Server Options struct argument.
  - All methods of creating servers (directly, ButtplugRemoteServer, servers in
  InProcessConnectors) have been updated to this format.
