code cleanup via dman gets rid of alot of cruft and most uses of htmltidy_empty() as well as initializing unset variables, etc.

Remove erroneous return t() (Issue #486122) and fix some outdated text and links on the page as well.

* move filter settings to "per format" settings like every other filter
* store the variables for per format as a multidimensional array
* move the help and delete the menu item associated with settings previously

create branch 'DRUPAL-6--1'.

- Pretty heavy rewrite. There was lots broken in the old version and this fixes some but probably breaks new stuff.

- Removed all the 4.6 compatibility code.
- Fixed some formatting and replaced "s with 's.
- Cleaning up settings page.
