Alfred 3.4.1 Build 860

What's new in this version:

WORKFLOWS:
Update Script Format JSON output with new features:
- Add per item (and per item mod) variables which are passed out of the object on actioning the result
- Add per mod customisable images (i.e. dynamically change the result icon when a user holds a mod key)
- Please note that, as the Script Filter XML output is legacy, it remains unchanged

Fix Script Filter default fallback image order if no icon specified in JSON/XML:
- Fall back to Script Filter icon first, then Workflow icon

Prevent incompatible workflows from loading in macOS 10.12.4+ if they contain an older version of 3rd party library Alfred-Workflow:
- Give link to troubleshooting page to automatically update and re-enable these workflows
- Use new separate view for 'no workflow' and 'incompatible workflow' display in workflow editor, giving more future flexibility
- Add new "Snippet Trigger" getting started guide to + button of the workflow editor
- Fix snippet database cache to correctly update when snippet triggers are duplicated
- Reduce workflow trigger connection constraints, allowing new Snippet Trigger to be connected to input objects
- Tidied rendering of hotkey object in workflow canvas, removing gradient
- Update workflow import message, notifying that snippet triggers are also stripped on new workflow import
- Improved workflow save performance, removing some unnecessary saves
