* If an address matches both a 'masq domain' and a 'directory domain', IsDirectory() now returns it as a directory domain regardless of which order they appear in the configuration.  This fixes a problem found earlier today on a site that had overlapping domain declarations, and entries weren't being added to the directory index.
* Also fixed the log message that displays when adding an entry to the directory index; now it only displays if the entry was actually written.
