Ride Plot Highlight Interval on Hover

.. As you mouse over the ride plot it will now highlight
   the shortest interval that that point is within.

.. If an interval has been selected in the sidebar it will
   refrain from hover highlighting as it is distracting

.. Also fixed up the way the highlight curve works so it
   has its own axis and works regardless of the data series
   selected.
Ignore entire ride interval on hover highlight

When hovering over a ride if there is an interval that defines
the entire ride (typical if coming in from WKO+) then don't
hover highlight it, since it is distracting and adds no value.
WKO+ Interval Markers

Rather than skip over the 'standard' interval markers because they
have such verbose names we now plot the vertical marker only.

This is to indicate there is an interval at a particular point to
signpost to the user that they can hover over this point to get an
interval summary.
QwtPicker SEGV possibly on missing axis

.. the series plot has no yLeft axis yet the plot picker
   is always attached to it.

.. Since we do ALWAYS have a yLeft,2 axis for the highlighter
   I've attached the picker to that instead.

.. This should hopefully stop the SEGV in qwtplotpicker::updateDisplay()

.. Will watch and monitor

QT5.2.1 Unified Title ToolBar Update

.. if you build with qt 5.2.1 then the unified title and toolbar
   is back, but its a hack to just change the gradient and use a
   standard toolbar .. so we do that, but make the colours match.

Histogram Polarized Zone Option

.. now can show in zones but using the polarised zones
   rather than user defined zones.

.. we may need to revisit this since it uses zone 2 rather
   than estimate LT1 from CP.

NOTE: The compare mode needs updating to support this option.
