Add functions addCondition and removeCondition to creature.ts to allow for better handling of conditions. Add remove_status field to CreatureUpdate, which is used to call creature.removeCondition. Add remove_status to logger.types.ts and move logging of condition removal to the logger

Note that comparisons on IDs is specifically not done in order to avoid problems with improvised conditions.

Changes Proposed
