Alfred-pyworkflow

Under Alfred 3, will now preferentially use the Workflow Version specified in Alfred's workflow configuration sheet (and `info.plist`). No `version` file necessary any more.

Improves behaviour when workflow scripts aren't run from Alfred and the corresponding environment variables aren't set.

Thanks to fantomnotabene for 92

- Support for setting workflow variables via Script Filter feedback
- Support for Alfred 3's advanced modifiers

**Note:** Both these features are Alfred 3 only.

Use `.alfred3workflow` files in GitHub releases for Alfred 3-only workflows. This enables you to release backwards-incompatible versions without Alfred 2 installations trying to update themselves to death.
