Patched PDA scanner to be more useful

PDA's integrated scanner was VERY rudimentary. Patched it to resolve
some formatting issues and improve usability. Patches #4522. The HTML simplification engine may be better in the helpers, but I'd imagine it's only used in this rare case.
Personally I agree (especially since ideas aren't copyrighted, fixed forms of ideas are.) But that was already in there and I didn't want to step on any toes by removing it.
