o do not require $JB_PACKAGE to be set to a bug category; if $JB_PACKAGE
is not set, the default category "test" is used
o the above will also fix the error messages on nbftp occuring in
update-distfiles (hi veego!)
o make proper use of "DEINSTALL" and "MESSAGE" files so that installing
(and deinstalling) of jitterbug from pkgsrc/as binary makes no difference
o when echoing the defaults for JB_USER, JB_USERID, etc, use the actual
variables, not hardcoded values
o ownership of jitterbig.config fixed (@JB_USER@ instead of root)
