Old PLOTTER::Text is not (yet) removed, but it use negative text size
to mirrored text, which is not really compatible with some plotters (especially PDF).
Using TEXT_ATTRIBUTES is much easy and much better,
so PLOTTER::PlotText() is added.
Note: "old" PLOTTER::Text() is not removed yet.
EDA_ITEMs are responsible for giving their parent a crack at it if
they failed to resolve it. This recurses all the way up to the schematic/
board, and then to the project.
Cross-reference handling is also move to the EDA_ITEMs. It must be done
before bubbling up so that we don't end up in loops. (The aDepth parameter
will break the loop, but without having done anything useful.)

Since EDA_TEXT is a base class, we can just force the child classes to pass the correct iu scaled size
ALLOW_BOLD_THICKNESS removed because it's a pre-custom font holdover
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.
The problem is that "real" page numbers can be duplicated, so we work around it
by using virtual page numbers instead which are guaranteed unique.
Example "goto:3" will go to page 3. If customised page numbers are used such as
a, b, c, then to go to page b, we should specify goto:2 (i.e. the virtual page
number).
Also fixes some plot bugs with arcs.
Also moves polygonization of arcs (when required) in plotting code
from 5 degrees to calculated based on ARC_HIGH_DEF.
