Fixed a number of issues with data from quarqd inf and nan values where
inserted as valid data points and thus destoying all plotting in the
realtime window and in later analysis.
The unit was used to distinguish between the entities, thus rpm was
erroneously used as a cadence, rpm is used as the unit for wheel
rotation and for cadence. This made the cadence useless together with a
PowerTap hub which reports both cadence and wheel rotation.
No error checking was performed on the received data, bad data is
ignored now.
The left side of MainWindow is now a toolbox which contains
Ride Analysis and Racing and Training options. The Right side
tabs have been reorganised and associated with the toolbox.
To support the population of the Racing and Training left tool
the config dialog has been updated to enable the user to configure
the location of their workouts.
In addition, the config dialog now calls upon MainWindow to issue
a configUpdate() signal to notify widgets when config has been
updated. This is a refactoring of the existing mechanism that
only called realtimeWindow->updateConfig, now any widget can
connect to the MainWindow signal and re-read its config appropriately.
Currently, the TrainTool and RealtimeWindow widgets have been coded to
use this.
