og_blueprints 5.x-1.0-alpha6

Changes since DRUPAL-5--1-0-ALPHA5:

• #261855: Fixed deprecated use of call-time pass-by-reference. (Also a bunch of whitespace cleanup)
• Utilize proper lowerCamelCase for all methods.
• Fixed crufty call to old method; paint_over_it() was still in there, was refactored to retain().
• Fixed flipped logic for the blueprint creation button (update vs. create new).
• #270278: Fix to the instantiation routine that was causing errors for releases that had no panel displays in them.
• Rolled back small unintended change to the instantiator.
• Missed one method name refactor; also fixed the final, most-pressing bug in relation to #270278.
