Project feedback in cpm

Description

Fixes project-level feedback not appearing in CPM (or actually, all feedback targets using generic server-side report formatting).

This was an unregistered critical-level UI bug.

Additions

A method getAllEntities returning all entities in the project. This is the equivalent of getAllChildren and adding the project entity to this set.

Changes

Changed generic report formatting and benchmarking from getAllChildren to getAllEntities.
