I have been continuing to conflate 'the current state of the service'
vs. 'the result of the last command the service ran'. The latter may
still be useful to report back to the clients, but the manner I've
used this in so far has been more in line with the former. So let's
consistently Make It So.

Redo notifier menu items: they now show relevant dialogs, with buttons to perform query/sync actions

We use the existence of WpkgCmd (presumed to be on the network share)
as a suitable proxy for this check.

This will copy all the status lines to the clipboard.

All of this was cobbled together copy-pasta. Lets try again
at desiging the communication properly now I've experimented a bit.

I had conflated the data structure I wanted to use for sending a
request to the service vs. having the service be able to respond.
This is the first step to separating out the two.
