Turns out cups caches any remote printers it sees and uses that cache
even if browsing is disabled.  See the bug report for more info.

This appears to work properly (and as I hoped it would).  Browsing
works when enabled but printers are only shared if ports.conf is
modified.

A UI to enable sharing would be nice, but certainly not needed for
dapper.  UI for controlling per-printer sharing would be good too
eventually.
