    Travis - fix failure to load some libraries while running scm tests
    
    In the travis environment (guile 1.8 in combination with other unidentified,
    particular package versions) the scm based tests are looking for
    backend modules (xml and dbi) in the installation prefix instead of
    in the build directory. Explicitly setting the environment variables
    GNC_BUILDDIR and GNC_UNINSTALLED fix this. I haven't figured out why this
    is not needed on all platforms/tool version combinations. But the fix
    works in all (autotools based) cases. CMake builds may need a similar
    fix, but I don't know that environment sufficiently to implement it.

    Bug 759934 - Tiny reports in HiDPI
    
    While a proper solution is only possible with a more recent
    version of webkit, this commit will allow users to work around
    the issue by manually setting a default zoom level for reports.
    This setting can be found under
    Edit->Preferences->Reports
