Bugfix use ready event in quotes

The quotes app didn't follow use the ready event, so I went in to fix that.  But I also:

- Deleted build files, at least for quotes
- having a shared .gitignore, to avoid adding back build files
- improved the App Message sync system

As usual, you probably want to read commit-by-commit for my changes.  Some of them are just nuking files, which makes the change look even larger than it is.
