Partial transfers

Added

• We have added a new route, /resource_types/[id]/resources/[id]/items/[id]/partial-transfer; A partial transfer allows you to transfer a percentage of the total for an item from one resource to another.
• We have added an item_transfer table; the table will log which items were transferred and by whom.
• We have added a partial transfers collection; the route is /resource_types/[id]/partial-transfers.
• We have added a partial transfers item view; the route is /resource_types/[id]/partial-transfers/[id].
• We have added a transfers collection; the route is /resource_types/[id]/transfers.
• We have added a transfers item view; the route is /resource_types/[id]/transfers/[id].
• We have added a delete endpoint for partial transfers.

Changed

• We have reformatted the validation rules in the configuration files; easier to read and simpler to add additional rules.
• We have switched the HTTP status code for a "Constraint error" from 500 to 409.
• We have tweaked the description for the resource field in the /resource_types/[id]/resources/[id]/items/[id]/transfer OPTIONS request.
• We have renamed the third parameter of the route validation methods; we changed the name from $manage to $write.
• We have renamed a response helper method; it was not clear from the name that the method is used for updates and delete.

Fixed

• It is possible to set the quantity for a simple-item item as zero.
• It is possible to clear optional values in a PATCH request.
