    libide: Fix parsing indent-tabs-mode in modelines
    
    If a modeline contains (for example) ‘indent-tabs-mode: t’, libide was
    explicitly setting IDE_INDENT_STYLE_SPACES. It was assuming that
    MODELINE_SET_INSERT_SPACES being set meant that spaces were in use,
    rather than the intended meaning of options.insert_spaces being
    meaningful.
