In Media preflet:
* Refactor MediaListItem into four/five classes:
* MediaListItem : abstract base class which provides an interface for
MediaWindow and MediaListItem subclasses
* NodeListItem : list item for media nodes
* DeviceListItem : list item for audio/video settings (device selection)
* MixerListItem : list item for the audio-mixer
* MediaListItem::Renderer : does the drawing of MediaListItems, which supply
render paramaters via a 'SetRenderParamaters()' method.
* Comparison of MediaListItems (for sorting) is done via double-dispatch
* MediaListItem provides a pure virtual AlterWindow() method, which removes the
burden of distinguishing between different behaviours from MediaWindow.
* Add methods to MediaWindow for the MediaListItems to call in their
AlterWindow() implementation, eg. SelectNode()
* Seperate code into these methods, as well as a few private utility methods.
* Add a RAII-style 'SmartNode' nested class for MediaWindow, which handles
watching/unwatching allocating/deallocating of media_nodes

In Media preflet:
* Move icons to resource file.
* Add MediaIcons class to handle loading and storing the icons.
* Use a MediaIcons object in place of a BList for passing icons to our list items.
* Add IconHandles.h to hold an enum for identifying icons in/from our resource file.
* style fixes
