Fix ScatterPlot setTime() SEGV

At first it seemed this was caused by setting the time to
a value greater than the length if the ridefile.

It was actually a constructor error, since the settings
class didn't initialise the ride variable.

Remove Column Chooser from Chart Settings

Because the chart settings are modal its a really bad
idea to open up a column chooser from there. So, by
default, we don't have a column chooser option on the
search/filter box -- it must be explicitly requested.

We therefore explicity set the column chooser from the
mainwindow and also from the ride navigator window.

Add KK roller wheel size option

Adds another option the the selection of wheel sizes: the 2.125" roller
on Kurt Kinetic trainers. Should be 169.56mm, but rounded up to the
nearest integer as 170mm.
The reason for adding this is to support users of Kurt's InRide sensor,
or people putting an ANT+ sensor in the same location.
