Miscellaneous fixes for cf-sketch

- Bumped version number
- Better messages in sketchify, including recommendations at the end.
- Better syntax for "define params" command
- Search now searches the entire JSON of the sketch, not just name and description
- Add CFEngine::stdlib automatically to dependencies in sketches produced by sketchify. We will remove CFEngine::stdlib eventually, but for now it's necessary to include the dependency for the sake of standalone runfiles.
