Replaced FontAwesome with integrated SVG icons. (#18)

* Removed dependency to FontAwesome and embedded icons as SVG directly.
* Support dark mode for callout alert style.
* Moved alert type naming from 'danger' to 'attention'. Introduced type mappings to support mapping further alert type keys to existing definitions, e.g. map legacy alert type 'danger' to new type definition 'attention'.
