Renamed `uikit` module. Auxiliary dialogs `streamedit` and `search` moved into plugins. Less indentation. Compacter import statements. Core plugins initialized into .features, and grayed out in configuration dialog. And `station_context_menu` moved into method. check-in: f5f0ae18c1 user: mario tags: trunk
