This change cleans up the structure of the Options struct in order to clearly delineate which options should be configurable for the user. Follow-up work is needed to refactor the completion options to fit into this structure, as well as to make sure that the name of the field is the name of the setting. This will make it easier to generate markdown documentation from the code. Also, remove options that are no longer in-use and mark them as deprecated.
