EDA_ITEM is a child of VIEW_ITEM, so a static_cast is not appropriate,
since in some cases it could be called with a non-EDA_ITEM argument.
This was triggering an ASAN heap-buffer-overflow in GerbView.
This way, when the user changes their color theme, any sheets
that did not have a specific color set will change with the theme.
Also add a button to clear color overrides from a sheet, because
any schematics that have been saved before this change will have
the colors set to something other than UNSPECIFIED.
ADDED Eeschema-specific netclass settings including wire and bus
thickness, color, and line style.
Netclasses override individual wire & bus colors and line styles.
If that proves an issue we might look at something more sophisticated
with inheritance.

Remove extraneous use of FLAG0 from tracks cleaner (it was checked but
never set).
Fix issue in expand connections where two parts of it couldn't agree
on the same flag (BUSY vs SKIP_STRUCT), and where the second part was
clearing the flag instead of setting it.
Remove obsolete HIGHLIGHT infrastructure (we now use selection).
Remove extraneous use of BUSY flag in several places (it was never
set).
Add missing plot and print changes for the new bus entry properties.
ADDED: Junction properties diameter and color can now be edited.

Set up a new lineage for SCH_ITEMS to get back to the SCHEMATIC
they live on: Items will all be parented to the SCH_SCREEN that
they are added to, and each SCH_SCREEN will point back to the
SCHEMATIC that it is part of. Note that this hierarchy is not
the same as the actual schematic hierarchy, which continues to
be managed through SCH_SHEETs and SCH_SHEET_PATHS.
Also fixes a bug where a bunch of eeschema settings weren't getting
loaded because it looked like they were larger than the max value
(which wasn't being scaled from mils to internal units).

Texts were drawn with a minimal line thickness = GetDefaultPenWidth().
The default pen width can be to large for small texts.
So the actual text thickness is now always clamped.
Don't try to use complex algorithms taking into account default
margins, line-widths and pen-widths (especially when they differed
between label types). We now use the (user-controlled) text
offset ratio to determine the margins (from the center-point of
the attached line).
Some graphic line thickness were initialized to 0.
The actual line thickness is set after reading config.
But in some cases the config does not exist, and 0 line thickness creates draw issues.
