• Order is now determined by properties in default-settings.json
• Adds support for custom components

Even though order of properties isn't guaranteed, it mostly is in order. Now the order is determined by the properties in the configuration.

Support for custom components is added.

To add a new component:

1. add a file + contents to ./lib/custom-components/
2. add the component to ./lib/custom-components/index.jsx
3. add configuration item to ./custom-settings.json with an object containing at least

   { "name": "componentname", "enabled": true }
