implement player poses (sneak/sprint)

Browse Source 
* Added sending player metadata with poses to everyone

* Renamed sendPlayerMetadataToAll to broadcastPlayerMetadata

* Made entity metadata system flexible

* Made broadcastPlayerMetadata create new metadata instead of using a global one

* Moved writeEntityData, sizeEntityData and sizeEntityMetadata to procedures

* style nitpicks
