    Replace Math128 with GncInt128, add GncRational to Doxygen docs.

commit 089817a9f6d0aeeeeb563933390afda5d3d6fff9
Author: John Ralls <jralls at ceridwen.us>
Date:   Sat Oct 31 15:53:32 2015 -0700

    Templatize the GncInt128 constructors.
    
    Allows single or pair of arbitrary integral types to construct, without
    explicitly creating all of the possibilities.

    Clean up bitrot to get CuteCash building again.
    
    1. Use guile-2.0 instead of guile-1.8.
    2. Set GNC_PLATFORM_POSIX on Unix (for gnc_timezone.cpp).
    3. Pass guile include files when compiling cutecash.
    4. Link Boost libraries.
    5. Add -std=gnu99 to CMAKE_C_FLAGS.
    6. Temporarily put -O2 in CMAKE_C_FLAGS since Fedora requires
        optimization for FORTIFY_SOURCE.  (Eventually with CMake
        we will have separate Debug and Release builds.)
    
    Tested that cutecash builds and launches on OS X, Fedora 23 and Ubuntu 14.04.3.
