    ls: Use libide's files symbolic icons override
    
    Currently it only uses the icons from the default icon theme, so it
    doesn't show up the same as in the project tree or opened files list.
    
    So this commit makes use of those overridden icons with
    ide_g_content_type_get_symbolic_icon().
