[stevieb9]

• Method to store keys/values from registry (options?)
• Method to update existing values in upgraded config file (options key val?)
• Method to update new directives from upgraded config file to registry (options-update?)
• Push updated config file values to registry

[stevieb9]

• Run options-update to dump new config keys to registry
• Cycle through validOptions array, and store all key-value pairs in dict
• Write out this data to the config file
• Run options-update-force
