Add a reset button that will only show up if the user
edits the JSON configuration for grids. This is a temporary
measure until we have a real grid editor GUI in V7.

New strategy isolates all draw/don't draw decisions to the ViewGetLOD
routines, and all dimmed/not dimmed to PCB_RENDER_SETTINGS::GetColor.
The actual drawing in PCB_PAINTER is more-or-less conditon free.
Also adds new layers for pad and via hole walls so that they can be
controlled for high-contrast mode.
Also changes the drawing paradigm so that the pads are drawn even when
not on the high contrast layer, just in low contrast. The hole wall
is drawn in high contrast. This actually makes things clearer to the
user (although to be honest was done to keep from having to re-render
pads when the high contrast layer changes since we have two separate
layers now that we can adjut colours on).

wxFile is dangerous, it's ::Write method is a direct map to the write syscall. It does not handle partial writes!
This must be handled in our code which we don't.
This will always show 1 unit from each system, with the primary unit
being the current frame unit and the secondary unit being the
most recent unit used from the other system. These are saved in
the settings, so they are saved between runs.
Using CopyFile() that can collide with a windows header create hard to
understand errors, including link errors.
Renaming this function avoids these strange errors.
These settings objects could be created in a constructor/destructor
so we should catch the exception since those are noexcept.
Also change the settings trace to match the other kicad traces
as KICAD_SETTINGS
This exception will probably never be thrown in real life,
but the constructors are normally noexcept, so throwing
any exception from the json library causes Coverity to
have a fit.
You can now enable and disable snap to grid when drawing/editing across
all apps. You can also tie snap to grid to the visibility of the grid
to allow rapid enable/disable via grid display.
