* Will create an onsubmit attribute if it doesn't not exist. If it does, default action suppression
* will be appended.
* - `onsubmit` Used in conjunction with 'default' to create ajax forms.
* - `inputDefaults` set the default $options for FormHelper::input(). Any options that would
* be set when using FormHelper::input() can be set here. Options set with `inputDefaults`
* can be overridden when calling input()
* - `encoding` Set the accept-charset encoding for the form. Defaults to `Configure::read('App.encoding')`
*
