Update Quilt providers to version 2.2.5
Reflect current dashboard terminology in help text

Update admin help text to refer to "Janrain dashboard" rather than
"rpxnow dashboard", for example.
Update jQuery on "prefill from..." form field

Should be using "prop", not "attr" to disable/enable form field. Also
this.checked wasn't working on latest Chrome; update to use jQuery :checked
pseudo-attribute.
Add modeline to all php files

Just cause I'm not using WP coding standards in my default environment,
and I want to make sure I don't mangle these files while editing them.

Also move around some whiteapace for fun.
Remove a lot of commented out crud from field list
