Tor silently ignores hidden directory when it isn't writable
I added HiddenServiceDir and HiddenServicePort to torrc.
When the empty HS directory has permissions 0600, tor starts without creating the HS and without complaining. It should either fail to start, or print a warning that the HS directory isn't writable.
When permissions is 300 though, tor complains that 'Directory x cannot be read'.
