Upgrade to QWT 6.0.1, but still uses a locally patched copy
since support for 8 axes has not been included, despite it
being a relatively simple patch.
Fixes#634.
Fixes#567.
Updates to the version 3 split activity wizard to bring it
back in line with the original v2 functionality;
* Splits at markers, rather than extracting intervals
* Shows a small plot to show the split visually
* Will automatically mark gaps rather than work between gaps
This will not be backported to v2 since the functionality
is working, albeit difficult to understand for this casual user.
Update to a number of plots to align with
the flatter, less cluttered chart style
used elsewhere (Ride, Histogram, CP et al).
Changes made are purely cosmetic and apply
to:
* Aerolab
* HrPw
* Realtime, ErgFile
* Weekly Summary
