TODO:
****Implement BandProxy methods
****Add QueryStatus handler for built-in bands
****Enable/Disable up, search, and folders commands appropriately
  **Why are explorer toolbar separators a nonstandard width?
  **Remove "(Empty)" item from Favorites menu. Probably something missing in CMenuCallback::CallbackSM
  **Chevron menu on menuband doesn't work
  **Fix CInternetToolbar::QueryBand to be generic

****Fix context menu to strip divider when menu shown for menu band
****Fix context menu to have items checked appropriately
****Implement -1 command id update
****When bands are rearranged, resize the internet toolbar and fix height of brand band
****Right clicking on the browse back and forward toolbar buttons displays the same as pulldown menus
    Implement show/hide of bands
    Why is the background color of my toolbars different from explorer?
    Internet Toolbar command handler should get the target for the command and call Exec on the target.
        For commands built in to the Internet Toolbar, its Exec handles the command
    When window width is changed, brand band flashes badly
    Add all bands with correct ids (system bands now add with correct ids)
    Implement IBandSite
    Implement remaining IExplorerToolbar methods
    Fix toolbar buttons to enable/disable correctly
    After toolbar is customized, it may be necessary to patch the widths of separators
    Add theme support
    Check sizes and spacing of toolbars against Explorer
    Implement resizing of the dock bar
    Add missing icons for toolbar items
    Draw History item in forward/back dropdown menus with icon
    Fix toolbar customize dialog to not include separators as possible selections
    Implement save/restore of toolbar state
    Refactor drop down menu code to use a common function since code is so similar
