Animator Inspector: Help boxes are misaligned and use technical code names

Steps to reproduce:

1. Create a new project
2. Add a cube in the Hierarchy window
3. Select a cube and create an animation for it (Window -> Animation -> Animation -> Click "Create" button -> enter animation name -> click Save)
4. Close the Animation window
5. Open the "Animator" window (Window ->Animation -> Animator)
6. Select the animation object in the Animator window
7. Go to the Inspector window
8. Check all the listed "Parameter" items
9. Observe the help boxes

Actual results: The error message uses the unformatted class name "AnimatorController," and the help boxes are incorrectly indented, causing them to be misaligned with other Inspector properties.

Expected results: The error should use the human-readable string "Animator Controller" and the help boxes should be left-aligned

Reproducible with versions: 6000.3.11f1, 6000.4.1f1, 6000.5.0a9, 6000.6.0a1
