Android uses qmake and apparently that doesn't support source files
with the same name. We already have chart/chartitem.*.

Move most of the QtQuick code to its own directory, so that it
can be reused in the future for the chart.

To enable rudimentary theming, collect all colors in a new
theme class. The class has to be passed down to the various
items.
In general the items save a reference to the them in the
constructor. Alternatively, they might also just query
the StatsView everytime they need to access a color.
For now, it's hard the say what is preferred: a reference
per item or a function call per invokation?

This is not perfect - the polygon of the confidence area is
calculated even if it is not shown. Oh well.

Render the confidence area and the regression line into a pixmap
and show that using a QSGNode.
It is unclear whether it is preferred to do it this way or to
triangulate the confidence area into triangles to be drawn by
the shader.
