BookmarkablePageLink :: setParameter int versions missing

the new URL handling & page parameters allow to use an integer index (great!)
however this has not been implemented in BookmarkablePageLink, so this needs to be added

private void setParameterImpl(int key, Object value)
{
if (parameters == null)

{ parameters = new PageParameters(); }

parameters.set(key, value);
}

and

public MyBookmarkablePageLink<T> setParameter(final int property, final String value)

{ setParameterImpl(property, value); return this; }

(and the same for int and long values)
