Updated Merge Tool Part 2b of 2abc

.. need to save away with analyse() and combine()
   now complete, and working pretty well on my data

.. now to work on the last piece, the 'adjust' page
   to shift data-series left and right manually (for
   cases where the calculated offsets are wrong or
   need to be tweaked by the user)

Fix Gear Ratio SEGV - addition to Hack Fix

... handle Gear Ratio as part of the existing logic - just without
smoothing
... solves SEGV problem in Compare Mode (and probably other areas of
AllPlot)
Updated Merge Tool Part 2c (last part)

.. UX to adjust now complete.

We may need to tidy a few things up, but this
is now good for working with the Moxy at the
very least.

Fix AllPlot Fill setting

.. was not always set, lost when removing the reference
   to parent->paintbrush in recent update.
HACK: AllPlot SEGV Fix

.. line 1289 of AllPlotWindow was updated to rebuild the
   plots when the ride was dirty, but it looks like there is
   a strange interaction when rideItem doesn't change and
   rideItem->ride() does.

NOTE: rides will not be refreshed after merge wizard completes
      until this is fixed up in AllPlotWindow.
Tweak Merge Adjust Code

.. logic error mean't the merge adjust only applied
   in one direction and also when ride got longer
   or shorter it was not reflected on the plot.
MergeAdjust give user more rope ..

.. and they will hang themselves !

.. seriously, the limits to the merge offsets
   added no real value but would annoy a user
   where the rides needed to be aligned to a
   greater proportion.

.. adjust can shift the offset for the entire
   length of the ride
