Use MCI_HWND & MCI_HDC in resource files

This patch introduces MCI_HWND, MCI_HDC and MCI_PALETTE in the
resource files.  The MCI parser still need be fixed to handle them.

In particular, the parser performs incorrect offset calculations
around the MCI_HWND element in the
L"handle\0", 0x00010000L, MCI_CONSTANT,
L"default\0", 0x00000000L, MCI_HWND,
L"\0", 0x00000000L, MCI_END_CONSTANT,
construct in MCI_DGV_WINDOWS_PARMS.  Obviously, the contents of the
CONSTANT block must be scanned to determine the offset of the union.
Don't try "window x text foobar" prior to that!

I'd be glad if Octavian would jump in.  I don't find time for a
rewrite but I've written many parser (unpublished) tests that show differences
between native and Wine.  My conclusion is that native's parser cannot
be implemented as the simple loop across the resources that Wine uses.
Yet I believe Wine's loop is enough for what apps require.
