    Bump minimum Gtk version to 3.18

commit c1324304cadd3ed270ab00999121d26b0ec69ee4

    Use Ubuntu 16.04 as oldest testbed on travis
    
    This needed a few tweaks to the docker file worth mentioning:
    - tzdata is not installed by default, resulting in test-gnc-timezone to fail
    - there were a couple of debconf warnings
      * missing apt-utils package => added it to the list
      * no interactive terminal for autoremove => forced non-interactive mode
    - in addition I have made building the docker file more verbose in order
      to catch such issues more easily in the future. If this turns out to be
      too distracting I can undo that part again.

commit d3e03ff6629e3f9bfd80cba1d8d02c0e9d6c8ff7

    Drop code to migrate preferences from gconf to gsettings
    
    This change was introduced in 2.6. Anyone wishing to migrate from 2.4 to 4 should
    first pass via 2.6 and/or 3 anyway so this code will never be used again for 4.x

commit 8aa696223bc01b908db31a910ab1c454a65bbdf8

    Always add share/scm to GUILE_LOAD_PATH
    
    Any scm file that will be built may need access to other scheme files that may have
    been linked into that directory. As it was only scm files that would be linked
    themselves would also be built with the search path set, causing other linked files
    not to be found for an scm file that doesn't add a link for itself.
