Bug #1013: WAxis labels for DateTime scale

Description

I believe there to be a bug when using the DateTime scale on WCartesianChart.
The following line in getLabelTicks() will never return true for units smaller than days due to the ordering of the unit enumeration.

bool atTick = (interval > 1) || (unit <= Days);

Enum:

enum { Days, Months, Years, Hours, Minutes } unit;

I've attached a patch file which I believe fixes the enumeration ordering.

reproduced (and fixed) the problem with this code:

WStandardItemModel model;

  WDate d(2009, 10, 1);
  WDateTime start(d, WTime(1, 0, 0));
  WDateTime end(d, WTime(1, 5, 0));

  WDateTime dt = start;
  int row = 0;
  model.insertColumns(0, 2);
  while (dt < end) {
    model.insertRow(model.rowCount());
    model.setData(row, 0, boost::any(dt));
    model.setData(row, 1, boost::any(row * 10));
    dt = dt.addSecs(60);
    row++;
  }

  plotTimeSeriesChart(&model, "minutes.svg", DateTimeScale);
