* Update ajv to fix #ref warning
* Consolidate ajv instantiation so config is always the same
* Remove propOrder flag for schema generation since its out of spec
* Refactor application input to use commando for extensibility
* Add all args/env as options for easy readout on command line
* Add 'check' command to allow running checks against a specific activity
* BC: must specify 'run' to run regular manager/unattended operation
* Generate individual schemas for root objects from config (Rule, RuleSet, Action)
* Using ajv validation means we can also report all validation errors
* Remove noisy generated guard files
* Return plain data (RuleResult) with setup (premise), boolean triggered, and optional result text/data (for later use in action maybe?)
* Use RuleResult to prevent running a rule that has already been run with the same setup (premise) -- will speed up execution and prevent extraneous api calls
* Get comment text from wiki page with 'wiki:' prefix in content
* Cache for 5 minutes (will make configurable later)
* Render comment content with Mustache template
