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
