Mark Liversedge 1e8b6edb62 Show kJoules, TSS/BikeScore et al on Train View 
The refactoring of the realtime display last year
removed the display of metrics such as BikeScore and
kJoules.

This patch adds more metrics that can be displayed;
* Averages for; power, hr, cadence, speed
* KJoules of work
* Coggan Metrics; NP, TSS, IF, VI
* Skiba Metrics; xPower, BikeScore, RI, Skiba VI

Also included is an updated default layout to
include some of these metrics.

Fixes #231
