fix 3d plot performance issues

Browse Source 
Scrolling up and down the ride files is painfully slow when
3d is compiled in. This patch uses a setActive mechanism in
the same fashion as the pfpv and performance manager tabs.

Additionally, a recent patch to support user preferences for
units added a settings lookup that was called for every point.
This is also fixed.

fixes #16
