[Seaside] Calls to addParameter: in JQueryWidgetBox

[Henrik Johansen]

Hi!
A few of the widgets still use addParameter: (which used to be deprecated, now removed), instead of addField:.

It would be nice if someone with access to sthub/Seaside/JQueryWidgetBox has time to update the following packages:

JQWidgetBox-FancyBox-Core		( JQFancybox >> #callback: )
JQWidgetBox-JEditable-Core 		( JQEditable >> #url )
JQWidgetBox-Autocomplete-Core		( JQWBAutocomplete >> #url )

Cheers,
Henry
