Updated bad link in help text to user roles page.

added formatting to status message on admin submit.

this admin page implements its own variable settings process. why not use _settings hook? saves code duplication.

Now puts debug info on the right hand side (so it doesn't overlap the menu structure). Note that you'll need to patch admin.module to call theme_head() for this to work properly. Dries should be commiting a patch that does that shortly.

Patch to allow you to run output through HTML tidy twice (option). You need to do this in order to get the line numbers on errors/warnings correct.

Updated to add user permissions fields (use htmltidy on output | use htmltidy debug mode | administer htmltidy)
