XML Ribbon markup file

XML Ribbon markup file

The standard windows library ribbon interface is either constructed
at runtime or specified in an XML file.  Since we have a static
set of functionality in our ribbon, it is simplest to just use the
XML file.

This should duplicate the interfaces currently provided by the
MFC ribbon, though the menu items in the file menu are slightly
taller than they used to be.

Use uicc.exe to compile the XML to the binary format and produce
a kfwribon.rc resource file and kfwribbon.h header.
