* [FEATURE] Add theme support
This change allows users to select a theme for Authelia on start-up.
The default will continue to be the existing theme which is known as `light`.
Three new options are now also provided:
* `dark`
* `grey`
* `custom`
The `custom` theme allows users to specify a primary and secondary hex color code to be utilised to style the portal.
