/* How does highlighting work?
*
* HighlightManager manages a list of if-then rules used to highlight messages.
* Rule is represented by HighlightRule. Action ("then" part) is HighlightAction.
*
*
* HighlightManager is also used as a factory for Highlighter objects.
* Each ChatControllerBase has its own Highlighter.
* Highligher may be customized by using setNick(), etc.
*
* ChatControllerBase passes incoming messages to Highlighter and gets HighlightAction in return
* (first matching rule is returned).
* If needed, HighlightAction is then passed back to Highlighter for further handling.
* This results in HighlightManager emiting onHighlight event,
* which is handled by SoundController to play sound notification
