Log Message:
Modify the Courier services rc.d scripts so that:

   (1) they are more likely to do the right thing if the user sets
       rc_fast_and_loose; and

   (2) they pre-create any necessary directories prior to start the
       respective services.

Also, fix the path to the courierwebadmin binary in SPECIAL_PERMS for the
courier-mta package.

Bump the PKGREVISION.
