TODO:
  **Provide implementation of new and delete that use LocalAlloc
  **Persist history for shell view isn't working correctly, possibly because of the mismatch between traveling and updating the travel log. The
        view doesn't restore the selection correctly.
  **Build explorer.exe, browseui.dll, comctl32.dll, shdocvw.dll, shell32.dll, shlwapi.dll into a directory and run them for testing...
  **Add brand band bitmaps to shell32.dll
  **If Go button on address bar is clicked, each time a new duplicate entry is added to travel log
****The current entry is updated in travel log before doing the travel, which means when traveling back the update of the
        current state overwrites the wrong entry's contents. This needs to be changed.
****Fix close of browser window to release all objects
****Given only a GUID in ShowBrowserBar, what is the correct way to determine if the bar is vertical or horizontal?
  **When a new bar is added to base bar site, how is base bar told so it can resize?
  **Does the base bar site have a classid?
  **What should refresh command send to views to make them refresh?
  **When new bar is created, what status notifications need to be fired?
  **How does keyboard filtering dispatch?
  **For deferred persist history load, how does the view connect up and get the state?
    How does context menu send open, cut, rename commands to its site (the shell view)?
  **Fix browser to implement IProfferService and hold onto brand band correctly - this will allow animations.

  **Route View->Toolbars commands to internet toolbar
  **Handle travel log items in View->Go
  **Fix ShowBrowserBar to pass correct size on when bar is shown
****Fix SetBorderSpaceDW to cascade resize to subsequent bars
****Make ShowToolbar check if bar is already created before creating it again
****Shell should fill in the list of explorer bars in the View submenus
  **Add folder menu in the file menu
  **Fix CShellBrowser::GetBorderDW to compute available size correctly
  **When a new bar is shown, re-fire the navigate event. This makes the explorer band select the correct folder
  **Implement support for refresh. Forward refresh to explorer bar (refresh on toolbar and in menu is dispatched different)
    Make folders toolbar item update state appropriately
    Read list of bands from registry on launch
    Read list of bars from registry on launch
    If the folders or search bars don't exist, disable the toolbar buttons
    If the favorites or history bars don't exist, disable the toolbar butons
    Fix Apply to all Folders in Folder Options
    Implement close command
    Add explorer band context menu to file menu
    Add code to allow restore of internet toolbar from registry
    Fix code that calls FireNavigateComplete to pass the correct new path

    What are the other command ids for QueryStatus/FireCommandStateChange?

    Add handler for cabinet settings change
    Add handler for system metrics change (renegotiate border space?)
    Add handler for theme change and forward to contained windows

    When folders are shown, the status bar text should change
    Add code to save/restore shell view settings
    Implement tabbing between frames
    Fix handling of focus everywhere
    Most keyboard shortcuts don't work, such as F2 for rename, F5 for refresh (see list in "explorer keyboard shortcuts")

    The status bar doesn't show help text for items owned by frame during menu tracking
    Stub out frame command handlers
    "Arrange icons by" group is not checked properly

    When folders are hidden, icon is the same as the current shell object being displayed. When folders are shown,
        the icon is always an open folder with magnifying glass
    Fix bars to calculate height correctly
    Hookup policies for everything...
    Investigate toolbar message WM_USER+93
    Investigate toolbar message WM_USER+100 (Adds extra padding between parts of buttons with BTNS_DROPDOWN | BTNS_SHOWTEXT style
