Resolve "Update: Settings look (First steps) and New Colors!"

Refactoring

Trying to include the settings layout page was giving me circular dependency errors, because the settings-layout depended on the shared module, which depended on the translation module, which depended on the settings module

To solve this, I split up the settings module into:

• Settings module - for service logic
• Settings page module - for the actual settings page

Closes #473
