Dev Issue #240

Some minor changes.

Added an if before one preventDefault
`
                    //prevent following link
                    if(! this.options.disabled)
                    e.preventDefault();
`
This allows the link to be used if not in the Edit mode. So an input url could be live while not editing.

In handleEmpty changed text to html so that html elements like <img> which have no text can be used.

And for Issue #240 Added merging of default and config "params" when in submit() when submitting multiple fields. Lets you add other non editable fields like nonces  or actions etc.
