[HtmlUnit] Bug in HtmlCheckBoxInput.click()

[<Mik...@su...>]

In HtmlUnit 1.1 the default behavior of HtmlInput.click() is to submit the
enclosing form when there is no onclick event handler.  That is incorrect
behavior for all types of input elements except type="submit".  Since
HtmlCheckBox.click() simply calls the same function in the superclass, it
behaves incorrectly.
