Replace BaseMode convenience class by individual implementation.

Using the convienience class does not really save code and adds another
needless level in the hierarchy. This affects the three remaining BaseMode
users: Help, ProjectExplorer and HelloWorld.

-    \class BaseMode
-    \mainclass
-    \inheaderfile basemode.h
-    \brief A base implementation of the mode interface IMode.
-
-    The BaseMode class can be used directly for most IMode implementations. It has setter functions
-    for the mode properties and a convenience constructor.
-
-    The ownership of the widget is given to the BaseMode, so when the BaseMode is destroyed it
-    deletes its widget.
-
-    A typical use case is to do the following in the init method of a plugin:
-    \code
-    bool MyPlugin::init(QString *error_message)
-    {
-        [...]
-        addObject(new Core::BaseMode("mymode",
-            "MyPlugin.ModeId",
-            icon,
-            50, // priority
-            new MyWidget));
-        [...]
-    }
-    \endcode
-*/
-
-/*!
-    \fn BaseMode::BaseMode(QObject *parent)
-
-    Creates a mode with empty display name, no icon, lowest priority and no widget. You should use the
-    setter functions to give the mode a meaning.
-
