[orca-list] More command line options for your consideration

[Joanmarie Diggs <jdiggs igalia com>]

Hey again.

As I continue to work, I continue to think. (Not sure if that's a good
thing or a bad thing, but anyhoo...)

Some historical context: The reasons why we have orca -q/--quit and orca
-f/--forcequit are:

1. We had two processes to run Orca
2. Killing one process (the python orca) by pid wouldn't kill the other
3. pkill -9 and pkill -15 couldn't be used to kill Orca

What we have as of today (in master, modulo nits and such):

1. There is only one process to run Orca.
2. Killing that one process by pid kills it
3. pkill -9 orca and pkill -15 orca each work

So orca -f and orca -q are redundant. We still need replace, but do we
need specialized quit command line options?

Take care.
