Changed object CRUD order merged with iapp CRUD.
Changed object CRUD order merged with iapp CRUD.

Problem:
 -Current CRUD ordering of Add, Update, Delete causes errors when adding
  objects that conflict with objects that are being deleted.
 -Also Iapp CRUD operations should be integrated with the other objects,
  since similar conflicts can occur too.

Solution:
 -Change object CRUD ordering to match iapp CRUD (Delete, Add, Update).
 -Merge iapp CRUD with other object CRUD.

Fixes: #55
