Use AssetManager to manage icons

One of the new features of StreamController is the `AssetManager`
component, which allows users to override icons and other assets used
by the plugin in its settings UI.  Among other things, this allows
users to configure state-dependent icons from plugins instead of
overriding the icon per-button.  This patch implements
`AssetManager`-managed icons so users can configure them as they wish.
