Add `resolution` property to Path.jsonschema

1. Resolution provides a maximum step size, in seconds, for the CZML implementor to take when sampling the `position` property for path visualization.
2. Everything else is just due to java translation using latest CS2Java.

@kring This is what I just talked to you about.
@shunter I assume the Java changes are okay and just due to translator changes?  All unit tests pass.
