Update KUrlRequester::setMode() api docs
The underlying file dialog is created with mode: "KFile::File | KFile::ExistingOnly | KFile::LocalOnly" by default, which is what "fileDialogMode" is set to in KUrlRequesterPrivate constructor initializer list.
Thanks to yecril71pl for pointing the issue out on IRC #kde-devel.
Thanks to Friedrich for pointing out where the default is actually set, I was blind it seems.
