- RealShell is not reloaded during runtime (bugfix?)
- Container variables are now private(set)
- Initialization now also sets `webApi` property (new)
- It is only possible to run `bind` on a `Container` once now
(previously known as `prepare`)
- Preparation for upcoming WebApi to replace `curl` command
(for checking for updates)
The newer Swift native method is broadly supported and can properly
handle complex UTF-8 characters like emoji, whereas the old API does
not work correctly with emoji.
In most cases, this likely wouldn't have caused any issues but it does
make things a little cleaner now, and ensures we won't encounter emoji
trouble in the future.
