+The //PluginAbstract// class is the base class for all plugins usable with the Plugin Manager.
+Provides:
+  * installation / uninstallation
+  * updates
+  * configuration handling
+  * dependency checks
+  * autoload registration
+  * visibility + activation control
+All custom plugins should extend this class.
