/**
* Adds a generic button inline to the form. Does not do anything, you must add
* click handling code in JavaScript. Use a HTMLSubmitField if you merely
* wish to add a submit button to a form.
*
* Additional recognized configuration parameters include:
* - flags: OOUI flags for the button, see OOUI\FlaggedElement
* - buttonlabel-message: Message to use for the button display text, instead
* of the value from 'default'. Overrides 'buttonlabel' and 'buttonlabel-raw'.
* - buttonlabel: Text to display for the button display text, instead
* of the value from 'default'. Overrides 'buttonlabel-raw'.
* - buttonlabel-raw: HTMLto display for the button display text, instead
* of the value from 'default'.
*
* Note that the buttonlabel parameters are not supported on IE6 and IE7 due to
* bugs in those browsers. If detected, they will be served buttons using the
* value of 'default' as the button label.
*
* @since 1.22
