Add number of loaves of bread to bread razzia

[joandrsn]

For statistical purposes it would be nice to have a number of loaves of bread on a bread razzia.
This would make it easier for the person ordering the bread to determine how many loaves of bread is needed.

To be able to accurately determine how many loaves of bread is needed, the feature should also include a number of how many bread were left over.

For information today 117 fembers ate 16 loaves of bread in 42 minutes which was a bad experience for new fembers who came after the bread was gone.
