Please visit his website http://www.aadmm.org/fp-patch/ and read patch-description.txt to learn more about the details of the patch.
I adapted the patch slighty: It now does not just add a __construct() function to the existing class-named one, instead it replaces it completely. Therefore, some parent::__construct() calls had to be changed, too.
It involves how widgets work.
Now widgets must always be *registered* to work, even blockparser's.
Blockparser has got then a nice GUI to select which pages should be available as widgets; once the page has been enabled it is then available in the main widget panels
This solves the non-editable input things with non-firefox browsers: this way you just won't have the editbox anymore :P
I hope you'll like the changes.
There are many additions in lang files, so be careful to update (otherwise you'll get blank lines)!
