The CSM HUD PR caused some strange behavior including aborts due to parts of it using some slightly hacky code, the event refactor changing how events are processed and a minor oversight.
* Fix HP transport + some double <-> float problems
TOCLIENT_HP transport u16 hp as a u8, use u16 HP, this prevent HP over 255 to overflow across network
* Fix more double/float problem in serverpackethandler & remove implicit struct type for TileAnimationParams
* Fix connection unittests container
* Refactor clientevent structure
* Move structure outside of client header
* Create client events on heap not stack, this remove the ClientEvent object copy
* Use clientEventHandler to route events
