Added the option of supplying an array of ids and attributes to Base#update, so that multiple records can be updated at once (inspired by #526/Duane Johnson). Added the option of supplying an array of attributes to Base#create, so that multiple records can be created at once. Added that Base#delete and Base#destroy both can take an array of ids to delete/destroy #336. Added that has_many association build and create methods can take arrays of record data like Base#create and Base#build to build/create multiple records at once.
