Official production release

With the first official release, there is a small but significant change. The default directory for Sticky's persisted data files has moved from the local "/Documents" directory to "/Library/Application Support" per Apple's guidelines. Further, the files will live in subdirectory which will align with the bundle identifier of the implementing app. https://developer.apple.com/library/archive/documentation/FileManagement/Conceptual/FileSystemProgrammingGuide/FileSystemOverview/FileSystemOverview.html

**If you have been using Sticky already, please be aware that this will be a breaking change. Any persisted data will either need to be manually moved, overridden with a default location, or will be lost. **
