Progress updating to cv981/pv973:

* Implemented the new client AND protocol version methods.
* Implemented the new speed laws added in cv980 (http://www.tibia.com/news/?subtopic=newsarchive&id=2251).
* Added more missing bytea to login packets (client version/type and some unknown bytes).
* Fixed the InputMessage::getDouble method.
* Cleaned up some of the const values.
* Started on the pending state features.

TODO:
* Pending game state feature.
* Ensure version compatibility hasn't been compromised.
