Mineflayer

* use protodef aliases to properly define channels

* add bot.canSeeBlock (thanks Nixes)
* handle unknown entities and entities sent with their internal id
* add bloodhound to plugin list
* fix chat hoverEvent for 1.9

* added support for minecraft chests (thanks plexigras)
* cross version support : 1.8, 1.9, 1.10 and 1.11 now supported
* [BREAKING] prismarine classes (Block, Entity, Recipe, ...) are now available only by requiring them, not in mineflayer.X. It was required to make cross version possible. minecraft-data is also to be required directly and not available as mineflayer.blocks. The code depending on this should be updated, hence the major version.

* add actionBar event (thanks ArcticZeroo)
* added support for villager trading (thanks plexigras)

* bump dependencies

* update minecraft-data
