Porting the codebase to QT 5 (5.2) to get the
latest bug fixes, performance and improved platform
support.
This first part is to fixup the codebase to compile
on Qt 5, but some aspects have been broken (video).
The second part is to migrate from Qwt 6.0.1 to the
latest Qwt for multiaxis support.
The third part will be to fixup any platform specific
issues or issues identified at runtime.
This patch adds support for temperature and slope
across the ridefile readers.
For the most part their is no functional change
although it is now possible to view and edit these
data series in the editor.
File formats that can provide temp or slope include;
.bin, .fit, .srm, .sync, .wko
Further updates will be required to display the data
in the ride plot and histograms.
