Updated Grid API (#3399)

* Updated Grid API

Added Nonull/Nullable/Nonnegative where applicable.
Deprecated unused methods
Changed concrete classes with interfaces (HashMap -> Map)
IGridTickable will no longer accept null as TickingRequest. Do not
implement it, if it should not tick.

* Renamed parameter to match conventions
