Business Logic for Managing and Implementing Campaign Integration

At the highest level, users will be able to assign a Campaign to a Project. Child Activities will inherit the Campaign.

Support for nested Projects should be included. Whenever the value of a Project's Campaign is changed, that value should be assigned to child Projects; whenever a Project is assigned as a child of another Project, the parent's Campaign should be looked up so that the child can inherit it.

CRM_Volunteer_BAO_Project::create() should be modified to look up children if a Campaign parameter was supplied. The results of this lookup should be looped through and updated with the new Campaign value.

CRM_Volunteer_BAO_Project::create() should be modified to check the value of entity_table before saving; if the parent entity is a Volunteer Project, CRM_Volunteer_BAO_Project::retrieveByID() can used used to get the parent Campaign.

CRM_Volunteer_BAO_Project::retrieve will probably not need changes.

We should add units tests for these changes.
