Fix for Bug 6609, Clean up guided reports dictionary entry process

Some general interface cleanup tasks with the guided reports dictionary entry
process:

- Improving the breadcrumb links
- Eliminating the tabs in favor of more descriptive <legend> labels
- Clarifying some labels
- Correcting form markup according to established patterns

(Undertaken primarily because the tabs translated poorly when trying to
re-implement them for Bug 5481, Replace YUI JS libraries with Jquery UI)
