REVISION SUMMARY
  This is a WIP that I've been using on my personal branch for awhile. Figured I'd try cleaning it up and toss the diff up here.
  
  This creates a simple rectangular progress bar overtop the "size" column/text. When there's less than 5% space left, it will use a bright red fill.
  
  TODO
  ----
  
  - Need `m_spaceInfoObserver(0),` => `m_spaceInfoObserver(nullptr),`
  - Probably need `m_progressBar(),` => `m_progressBar(nullptr),` too unless that's calling an 0 param constructor there. Hmm.
  - I don't know how to properly reuse `mountpointobserver.cpp`, `mountpointobservercache.cpp`, and `spaceinfoobserver.cpp`. They're in `dolphinstatic_SRCS` and I need them in `dolphinprivate_LIB_SRCS` before `kstandarditem.cpp` is built. Do I need to have the statusbar link to the `dolphinprivate_LIB_SRCS` versions?
  - Colors are hardcoded. Red definitely isn't changeable, but the "outline" could be 20% from bgColor to textColor or something. The bg could be 10%. The "space filled color" could be the highlightColor. The red "you've only got <5% left" fill color is probably better to hard code though.
  
    painter.fillRect(rect, QColor::fromRgb(230, 230, 230)); // Background
    painter.setPen(QColor::fromRgb(208, 208, 208));
    painter.drawRect(rect); // Outline
    const QRect fillRect(rect.x(), rect.y(), rect.width() * ratio, rect.height());
    if (ratio < 0.95) { // Fill
        painter.fillRect(fillRect, QColor::fromRgb(38, 160, 218));
    } else {
        painter.fillRect(fillRect, QColor::fromRgb(218, 38, 38));
    }
