Subject: permit explicitly empty qt.conf entries

this allows expressing "no SettingsPath" cleanly, and makes the
internals cleaner.

this is marginally behavior-incompatible in that if somebody had Prefix
or Data set to an empty string (rather than a dot, which is hinted at by
the documentation and commanded by common sense), he would have gotten
the binary's directory resp. Prefix, while now it will be just empty.
