Standalone Features: MacOS

[baconpaul]

Standalone on MacOS works OK. You get a gui. It makes noise.

Here's a rough feature set I think would make it complete

1. You can choose audio and midi settings better than just "default" and "all"
2. Those settings get persisted in ~/Library/ApproriateThingy
3. There's an about screen showing the clap entry / description info for the hosted plugin
4. You can save and restore state

At a minimum

It may also be useful to do something with parameters. But that's less crucial.
