A new config pane for defining color preferences for chart
curves, shading, background and grid lines et al. Default values
echo the current hard-coded values.
And pay attention to MainWindow::activeTab, such that only the active
tab redraws itself when changing rides. This change really increases
GC's responsiveness when scrolling through the ride list.
This patch adds Aerolab, a virtual elevation module. A
new tab is added in which the user can perform virtual
elevation analysis. This version is a manual Aerolab,
where user can use the following sliders to elevation-match
to a known elevation profile:
Crr -coefficient of rolling resistance
CdA -aero coefficient of drag * frontal area
Eta -drivetrain efficiency (to be used when using a crank-
or bottom-brack-based power meter)
Mass -total mass of bike + rider
Rho -density of air
E_offset -an elevation offset to align elevations
