Entity related mappings

[Sychic]

Includes mapping most of living entity and entity classes. This includes parts of other classes which were referenced in those classes.

There is a conflict to fix:

METHODs net/minecraft/class_1297/[method_0_6892, method_5713]()Z -> checkWaterState

[thecatcore]

There is a conflict in 1.10.x, make sure all interfaces and abstract classes declaring method_5797/getDisplayName have the same name for it. Sometimes when a method is declared in multiple places, an entry needs to be created for each one in mappings with the same name.

See for example getName() which is declared in both Entity abstract class and BossBarProvider interface in old mappings.
