Hi !

    When using java applications such as sweethome3d on a 4K screen, the
    UI fonts are so tiny that they become unreadable. On the sweethome3d
    website FAQ (https://www.sweethome3d.com/faq.jsp) there's a section
    about "Texts in the furniture catalog are not displayed correctly or
    icons in the toolbar appear very small on my computer. How can I fix
    that?" which references a "SweetHome3D.l4j.ini"
    (https://www.sweethome3d.com/SweetHome3D-HiDPIx2.l4j.ini).

    So I updated the loader script for sweethome3d to read the
    ~/.eteks/sweethome3d/*.ini files and use their contents to
    start sweethome3d with my own fonts configuration.

    Here is the diff:

    Note that I can't make it use another Look&Feel and I don't
    know why (maybe I don't know how to).
