dot/bash_profile: Sensible default behaviour for `~/.mdw.conf' lookups.

  * For setting environment variables, don't bother if there's no
    configuration entry.  For NNTPSERVER, this now means that
    `.mdw.conf' overrides the system setting rather than the other way
    around, which I think is the right answer.

  * Locale things default to POSIX, just in case.
