DRAFT mcf: Recognize "-f CONFIGFILE" option, v2 of CONFIGFILE, and more (v7.0.0)
- Also allow CONFIGFILE to have a ".mcf" extension.
- Drop support for broken tags=
- Support CONFIGFILE version 2 (McfFileVersion = 2)
- Rename "webos_layers" to "Layers", but continue to recognize old name.
- Recognize dict-s for fetch and options, but continue to recognize
file version 1 strings.
- Recognize an optional BblayersConfExtraLines variable in CONFIGFILE
that contains a list of strings to be appended as separate lines to the generated
conf/bblayers.conf .
- Rename "submission" item to "fetch".
- Fix error message to mention conf/layer.conf instead of incorrect local.conf .
- Correct/improve messages
- Requires Python 3.5 => major version bump.
