File selection dialog update, part 1

This adds a replacement for the SelectFilesDialog class.  It has
been updated to use Explorer-style dialogs, which are a bit nicer
than the old-style dialogs.  Hopefully this will eliminate some of the
brain damage, like the disappearing Accept button.

This change only updates MDC.  A second change will update the main
app and remove the old code.

Also, updated the MDC version to 3.0.0, and changed the web site
linked in the Help menu from faddensoft.com to a2ciderpress.com.

/*
* Support for file selection dialog.
*
* What we want to do is get the full set of selected files out of the dialog.
* However, Windows does not provide a way to do that. There are various
* slightly awkward approaches:
*
* - Get the IShellView pointer via the IShellBrowser pointer via the
* undocumented WM_GETISHELLBROWSER message. You can then play with the
* shellview window, select items with SelectItem(), and get an object
* representing the selected items with another call. What form the
* object takes is frustratingly unspecified.
* http://www.codeproject.com/dialog/select_all_button.asp
* - Get the CListView so you can play with its members. This is done by
* GetParent --> GetItem(lst2) --> GetItem(1), which is probably
* somewhat fragile, but seems to work on 98 through XP. Standard LVN
* stuff applies.
* http://www.codeguru.com/mfc/comments/10216.shtml
* - Using a window hook (not an OFN hook), get the class name and strcmp()
* it for the class we're looking for ("syslistview32"). Once we have
* it, proceed as above.
* http://www.codeproject.com/dialog/customize_dialog.asp
*
* Care must be taken with the ListView because it doesn't contain file names,
* but rather display names (potentially without filename extensions). The
* next big assumptive leap is that the ItemData pointer is a shell PIDL that
* can be used directly.
*
* The PIDL stored is, of course, relative to the IShellFolder currently being
* displayed. There's no easy way to get that, but if we just go ahead and
* call SHGetPathFromIDList anyway we get the right file name with the wrong
* path (it appears to be the desktop folder). We can strip the path off and
* prepend the value from the undocumented GetFolderPath() call (which just
* issues a CDM_GETFOLDERPATH message).
*
* To make matters even more interesting, it is necessary to provide a "hook"
* function to prevent double-clicking from closing the dialog while side-
* stepping our additions. Of course, adding an OFN hook renders all of the
* existing message map and initialization stuff inoperable. You can stuff
* things through various "user data" pointers and end up with access to your
* object, and if you cram the hook procedure's hDlg into the object's m_hWnd
* you can treat "this" like a window instead of passing HWNDs around.
