ADDED Junction Size and Color to Edit Text & Graphics properties.
The added feature is only because it's the only way to recover from
the buggy behaviour having changed all your junctions to overridden
values.
Also adds help texts to the Junction Dot Properties dialog to
specify how to get schematic dot sizes and eeschema colors.
Also fixes the terminology in the Line/Wire/Bus Properties dialog
(the default widths come from the netclasses, not from eeschema).

Bitmaps are now identified by an enum class instead of by pointers.
Bitmap loading and caching is now handled by a class in common, and
we no longer compile most bitmaps into the binary, so there is no
longer a bitmaps static library.
Instead, bitmaps are archived to a .tar.gz file which is installed
in ${KICAD_DATA}/resources/images.tar.gz
The source PNGs are checked in to Git as the original CPP files were,
so that people can build without the required dependencies to convert
SVGs to PNGs.
Initial support is also added for dark theme icons, although this
is not yet exposed in the GUI.
Stubs are present for multi-resolution image resources, but this is
not fully-baked yet and could use some refinement.
CHANGED: In Schematic Setup->General->Formatting->Connections, added
pulldown for "Junction dot size" with values none, smallest, small
default, large, largest" Added support in "sch_painter.cpp" to not
paint junction when they have a diameter of "1" which is what "none"
sets as the diameter.
Add missing plot and print changes for the new bus entry properties.
ADDED: Junction properties diameter and color can now be edited.

Apparently the < operator was never implemented for SCH_JUNCTION objects
so they were not get sorted which was causing the large diffs between
schematic saves.

Scope: NETLIST_ITEM, CONNECTION_TYPE, ELECTRICAL_PINTYPE,
NET_CONNECTION, NETLIST_ITEM, GRAPHIC_PINSHAPE
Note, the pin type enum had PT_ added to the front to prevent
shadowing of the INPUT symbol on msys2 (see discussion at
c17c9960d8)
