When using the ckEditor WYSIWYG there is a button for adding an iFrame to the content. Preside also has it's own iFrame widget which allows us to better control the injection of the iFrame.
This task is to update ckEditor so the iFrame button opens the Preside CMS iFrame widget instead of the ckEditor iFrame dialog.
This will possibly also involve checking the widget is available so the user doesn't experience any issues when using the iFrame option.
Nice to have
A nice to have would be to setup the option for being able to configure dialog buttons for specific widgets also.
