refactor: Refactor route parsing and improve errors/warnings
refactor: Refactor route parsing and improve errors/warnings

Part of adding additional ‘transformations’ phase to processing:
parse —> transform —> generate (better code structure and testing).

Adjust some warnings from `sails.warn` to `sails.verbose`.

Correct shortcut blueprint route processing.

Add warning error messages for action documentation for actions which
do not exist.
