Whitespace changes.
Adds a comma back into journal formatter registration.

This one somehow got lost. But it definitely belongs here.
Removes acts_as_tree from planning elements.
Changes recycle bin to be triggered w/ trash.

Previously, destroy! would do what destroy formerly did, and destroy

destroy destroys from DB.

Removes obsolete method override.
Fixes remaining spec for circular structures.
Updates changelog.

Measure and display time for three things during the Rails boot process

The goal of this change is to increase visibility of boot times, so each
developer can see when they increase. It might also improve the waiting time
by letting the developer know what happens during the waiting time.

Measured things:
* require 'rails/all'
* Bundler.require
* OpenProject::Application.initialize!
