General code cleanups

* Use final for all message handlers, Client, LocalPlayer,
  Being::getType, Being::setPosition and Being::setMap.
  (avoids some warnings about virtual dispatch in constructors)
* Use auto in more places
* Use emplace_back instead of push_back in some places
* Use default member initializers
* Less else after return
* Removed superfluous .c_str()
* Removed type aliases that are only used once
* Removed more unused includes
