0.1.2

• New: Add Location enum
• Add FieldGroup::addLocation() method: The FieldGroup::where() method is not intuitive enough.
• Fix: Remove OptionsPage field groups deprecated register() method call
• Add static OptionsPage::create() & SharedFieldGroup::create() methods
• Deprecate the OptionsPage::register() method. It's done automatically on object creation.
