Remove --portmidi-list-devices and --portmidi-output-device

No longer necessary now that we have config files. Users who were using
commandline flags to have specific hardware setups can, in the meantime,
adjust XDG_CONFIG_HOME environment variable to cause orca to choose a
different config file. Eventually, we'll have a commandline option to
load a specific config file by path.

Passing --portmidi-list-devices or --portmidi-output-device now will
cause orca to exit with an error, and to give instructions on how to set
the device using the menu in orca.
