CVS commit by faure:
html/html_formimpl.cpp (setType): Implemented, to make it possible
to set the type of an input element created with createElement.
Partially inspired by WebCore's setType(), but for getAttribute("type")
to work, setType() must set ATTR_TYPE. So parseAttribute() has to call
another method which doesn't do that, which is now parseType(), to
avoid an infinite recursion. Testcase forms/input_setType.html
