Upgraded Qwt to 6.2 (branch: qwt-multiaxes) (#4427)

This commit is based on https://github.com/GoldenCheetah/GoldenCheetah/pull/3956
with the following additions / changes:
* Upgraded to the latest version of the multiaxes-branch, thus eliminating crashes of GoldenCheetah on startup
* Disabled the emitting of Layout Requests on geometry changes of QwtScaleWidget - without this, CPU utilization was up to 100% on one core
* Added the class SplineLookup, reusing small portions of code from Qwt 6.1
* Re-added the splines in WPrime and RideFile (resampling), using the new interface of QwtSpline
* Appveyor: qwt in cache-section now depends on qwt/qwtconfig.prin.in for refresh on version change

+Qwt 6.2.0
+=========
+
+0) Requirement for Qt >= 4.8
+
+1) Class Includes added
+
+Include files, that match the class names are available now. So
+it is possible to write "#include <QwtPlot>" now instead of "include qwt_plot.h"
+
+2) BSD License for examples
+
+Where possible the code of the examples is available under the 3-clause BSD License 
+
+3) MathML text renderer removed
+
+The code can be found at https://github.com/uwerat/qwt-mml-dev now and is intended
+to become a standalone lib. Anyone who is interested to workon it, please let me know.
+
+4) Spline interpolation
+
+The broken implementation of QwtSpline has been replaced by a bunch of classes
+offering all sort of functionalities around splines.
+
+The most popular spline approximation/interpolation algos have been implemented:
+
+	- Basis
+	- Cardinal
+	- ParabolicBlending
+	- Akima
+	- The one used in MS Excel
+	- Cubic
+
+An implementation of the de Casteljau’s algorithm has been added
+
+	- QwtBezier
+
+5) New plot items
+
+	- QwtPlotVectorField
+      A new type of plot item for vector fields
+
+    - QwtPlotGraphicItem
+      An item displaying a QwtGraphic image ( f.e used by QwtPlotSvgItem )
+
+6) Plot Canvas
+
+	- QwtAbstractPlotCanvas introduced
+	- QwtPlotOpenGLCanvas added to support QOpenGLWidget
+
+7) QwtPlotCurve
+
+	- QwtPlotCurve::FilterPointsAggressive mode added - a fast weeding algo
+      for huge datasets with increasing x or y values
+
+	- QwtPlotCurve::closestPoint is virtual now
+	- QwtPlotCurve: polygon clipping includes the painter clip
+	- QwtPlotCurve::setLegendAttributes added
+	- QwtValuePointData added for curves, where the x values are the index
+	- a couple of new QwtPlotCurve::setSamples alternatives
+
+8) QwtPlotSpectrogram
+
+	- QwtPlotSpectrogram::setColorTableSize added
+	- QwtRasterData::setInterval/interval changed into a pure virtual getter
+	- QwtMatrixRasterData::BicubicInterpolation added
+	- QwtMatrixRasterData::interval: API cleanup
+	- QwtHueColorMap, QwtSaturationValueColorMap added
+
+9) QwtPlotRenderer
+
+	- using QPdfWriter where possible
+
+10)
+	- LOG_MIN/LOG_MAX removed, use QwtTransform::LogMin/LogMax instead ( values differ ! )
+	- qwt_compat.h removed
+	- qwtFuzzyGreaterOrEqual/qwtFuzzyLessOrEqual removed
+	- qwtGetMin/qwtGetMax removed
+
+11)
+    - Not aligning unknown paint engines ( f.e EMF )
+    - QwtNullPaintDevice is using a different type than QPaintEngine::User now
+
+12) Many other changes ...
