- Add distinction between `getInstance` and `getInstanceOrCreate` since
it is not always possible to create an instance (since you might not
know the correct arguments)
- Remove all the `export const *Store = *Store.getInstance<*Store>();`
calls as it defeats the purpose of `Singleton`. Plus with the typing
changes the appropriate `*Store.getInstance()` is "short enough".
- Special case the two extension export facades to not need to use
`getInstanceOrCreate`. Plus since they are just facades it is always
possible to create them.
- Move some other types to be also `Singleton`'s: ExtensionLoader,
ExtensionDiscovery, ThemeStore, LocalizationStore, ...
- Fixed dev-run always using the same port with electron inspect
- Update Store documentation with new recommendations about creating
instances of singletons
- Fix all unit tests to create their dependent singletons
