feat(notification): display app errors, close #319 (#333)

* refactor(log): Refactor logging service

Removed the InjectionToken and changed LogService as default logger.
Finally ElectronLogService implements LogService directly.

* refactor: Optimize imports

* fix(app-update): Add missing rxjs imports

* style: Remove extra line

* refactor(store): Move app.actions.ts to shared module

* feat(notification): Add notification panel

Add angular-notifier to the app and created the ShowNotificationAction
to manage notifications

* style(notification): Fix tslint suggestion

* fix(notification): Add missing rxjs imports
