* Move MEMonitorHandler to internal code and fix some warnings
* Rename exceptions to conform to naming scheme
* Improved IGrinderRegistry
Added a builder for grinder recipes similar to IInscriberRegistry.
Replaced different add methods with this builder.
IIinscriberRegistry#addRecipe and removeRecipe now return true on success.
* Extracts item comparison from Platform into their own helper.
Renamed methods to be more more fitting for the actual comparison.
Added documentation about each methods behaviour.
Reduces the visibility of all fields to private and create setters/getters
when necessary. Exceptions are fields with GuiSync as these need to be
public.
Reduces the visibility of internal methods to private/protected/default when possible.
