Using arc angles to plot an arc is really error prone due to different
options between plotters, and angles defined in Kicad, using this version of
arc plotting from Kicad is no longer allowed in Kicad code.
Also moves most navigation code to SCH_NAVIGATION_TOOL.
Also changes page number href to anchor syntax ('#foo').
Also adds hypertext processing to SCH_TEXTBOXes.
Also adds combobox with schematic pages to text properties dialog.
It avoid trying to calculate arc angles (start, end or arc angle) that
frequently create issues due to reverse Y axis, plot mirrored and/or
angle normalization with different criteria.

These aperture macros were previously used but only for chamfered round rect.
They are now also used for custom pads (previously drawn as regions).
They are also optimized, i.e. only one aperture macro is created for a given shape.
(previously, one aperture macro was created for each chamfered round rect pad.)
So now all pads are flashed.
They are used for chamfered round rect pads, and can be used for custom shaped pads.
No actual change currently, but the shape rotation of custom pads and chamfered rr pads
can be now used in gerber plots.
Setting a line thickness = 0 for graphic objects (circle, rect, line) is
allowed but creates issues for circles that were plotted a non filled shapes
but having a outline thickness = 0.
plotter.h contains now only a header common to all plotters.
The code does not actually change, but it allows modifying a specific plotter
without recompiling most of kicad files.
