Make it (almost) possible to have more than one Dolphin KMainWindow

    Create a DolphinApplication, holding DolphinMainWindows and update
    the code to use the DolphinView to get the MainWindow, or get a ptr
    to the MainWindow directly. Or if all windows are effected go through
    the DolphinApplication to update every mainwindow.
    The UndowManager and ProgressIndicator have a rather strange relationship
    and will need some more attention but as UndoManager will be killed
    anyway I have skipped this.
    More cleanup, debugging and thinking is needed.

+Task:       Kill the Dolphin Singleton
+Reasoning:  Have more than one Dolphin TLW
+Approach: 
+    1. Create DolphinApplication to hold all TLW's.
+    2. Make dolphin.h dolphomainwindow.h
+    3. Change the Views to have a DolphinMainWindow
+       parameter
+
+Reasoning:
+    I find it more natural that the DolphinApplication
+    holds and controls the list of managed MainWindows and
+    will control the life time of them, specially deleting
+    them on exit.
+    The downside is that DolphinApplication and DolphinMainWindow
+    need to work together but this is managable
+
+    Making DolphinView::mainWindow() public. Most users of the
+    current Dolphin::mainView have a pointer to the current view
+    already. We could pass a second pointer for the mainwindow each
+    time but the same can be achieved by using the appropriate
+    DolphinView::mainWindow.
+    Another approach would be to ask the DolphinView to execute
+    actions on the MainWindow like it is done with declareViewActive
+    in DolphinView. I'm not entirely sure which one wins but currently
+    using mainWindow() does not show any negative impact.
+
+    2 times Dolphin::mainWin was used to check if the view is current.
+    this can be made a method of of the view
+
+    1 time we want the viewChanged signal of our mainwindow to update,
+    the UrlNavigator could connect a signal to a signal to allow this
+
+    12 times this was used to access the actionCollection
