Mark Liversedge a3f42c0746 Horizontal and Vertical Line Annotations on UserChart ...

.. annotate(hline|vline, "text", style, value) to add a horizontal or
   vertical line to the plot for the current series on a UserChart.

   style is one of solid, dash, dot, dashdot or dashdotdot which are
   the standard Qt pen styles for drawing lines.

   I also took the opportunity to refactor how annotations are passed
   from the datafilter down to the generic plot. This should make it
   far easier to add annotations in the future.

.. fixed a SEGV in the voronoi annotation, which was related to memory
   management and the sqrt_nsites variable (honestly, I am amazed it
   ever worked).

.. labels in Python and R charts are now broken, will fixup shortly when
   worked out how it should work (annotations are related to a series).
