Fixing initially disabled backspace in Firefo

Using Firefox, the backspace key doesn't work, until you type some text.

I fixed this by uncommenting the two commented out lines in fck_1_gecko.js:

// On Gecko we must disable editing before setting the BODY innerHTML.
FCK.EditorDocument.designMode = 'off' ;

and

// On Gecko we must set the desingMode on again after setting the BODY innerHTML.
FCK.EditorDocument.designMode = 'on' ;

Does anyone know why these were commented out in the first place?

Thanks,
Tom
