API: Track options and version
If options are not present in .api.json file (e.g. old PVP build), use an empty dict. If a message is used in CSIT, check its options. Tolerate vat_help, but print warning for others. This aims to discover in-progress and obsolete APIs. If .api.json version is not detected, or starts with "0.", add a "version" item to options, so they get reported.
