[CHANGE] Remove machine.m implementations of to-many relationship set…

…ters.

Mike Abdullah pointed out in http://www.mac-developer-network.com/columns/coredata/coredatajan10/ that Core Data on 10.5 and iPhone dynamically supply to-many relationship setters, so there's no reason to carry our own implementation. That's code that looks like this:

	- (void)addChildren:(NSSet*)value_ {
		[self willChangeValueForKey:@"children" withSetMutation:NSKeyValueUnionSetMutation usingObjects:value_];
		[[self primitiveValueForKey:@"children"] unionSet:value_];
		[self didChangeValueForKey:@"children" withSetMutation:NSKeyValueUnionSetMutation usingObjects:value_];
	}

	-(void)removeChildren:(NSSet*)value_ {
		[self willChangeValueForKey:@"children" withSetMutation:NSKeyValueMinusSetMutation usingObjects:value_];
		[[self primitiveValueForKey:@"children"] minusSet:value_];
		[self didChangeValueForKey:@"children" withSetMutation:NSKeyValueMinusSetMutation usingObjects:value_];
	}

	- (void)addChildrenObject:(ChildMO*)value_ {
		NSSet *changedObjects = [[NSSet alloc] initWithObjects:&value_ count:1];
		[self willChangeValueForKey:@"children" withSetMutation:NSKeyValueUnionSetMutation usingObjects:changedObjects];
		[[self primitiveValueForKey:@"children"] addObject:value_];
		[self didChangeValueForKey:@"children" withSetMutation:NSKeyValueUnionSetMutation usingObjects:changedObjects];
		[changedObjects release];
	}

	- (void)removeChildrenObject:(ChildMO*)value_ {
		NSSet *changedObjects = [[NSSet alloc] initWithObjects:&value_ count:1];
		[self willChangeValueForKey:@"children" withSetMutation:NSKeyValueMinusSetMutation usingObjects:changedObjects];
		[[self primitiveValueForKey:@"children"] removeObject:value_];
		[self didChangeValueForKey:@"children" withSetMutation:NSKeyValueMinusSetMutation usingObjects:changedObjects];
		[changedObjects release];
	}

I've deleted the machine.m code and moved the method declarations into a category named $_CLASS_NAME(CoreDataGeneratedAccessors) in machine.h to avoid "method not implemented" build warnings.

It probably would be nice to upgrade "contributed templates/rentzsch non-dynamic" to do the same (placing the machine.m code in
	if MAC_OS_X_VERSION_MIN_REQUIRED < MAC_OS_X_VERSION_10_5
	endif
blocks) but I'm not going to for this commit.
