Don't rename symbol libraries when performing a project "Save As.."
except for the legacy cache library. Changing library file names
breaks the symbol library table. This was the less painful option
than updating the symbol library table.

A note to developers, please do not set the minimum and/or size of bitmap
buttons. It causes bitmaps to get clipped using GTK on Linux. If the
bitmap button size is not acceptable, then supply an appropriately sized
bitmap rather than attempt to force the wxWidgets sizing mechanism to do
what you want. This almost always causes platform differences that do
not work well.
This provides a method to add symbols that represent footprints on the
board that do not have an associate component such as mounting holes,
fiducials, logos, etc that should be excluded from the bill of materials.
It also prevents those footprints from being removed from the board
accidentally when updating the board from the schematic.
ADDED: Support to exclude schematic symbols from bill of materials
export.
CHANGED: Derived library symbols will inherit optional fields defined by
their parent symbol and override existing optional fields.
CHANGED: The symbol editor will now only display the fields defined in
derived symbols rather than show mandatory fields inherited from the
parent symbol. Showing fields that cannot be edited would be confusing.
CHANGED: All mandatory fields in derived symbols can be edited. This
not only includes the field value but also all text properties.
Kill the dual datasheet variable storage which caused many datasheet
bugs over the years. The datasheet is now always stored in the data
sheet field.
In order allow the new file format to support derived symbols with
field properties that are different than the parent symbol, the code
that copied the parent field properties to the derive symbol field
properties had to moved out of LIB_PART::SetParent() into the legacy
symbol library plugin and the symbol library editor add new symbol
code to preserve the current behavior and not overwrite derived
symbol field properties.
This lays the ground work for allowing field properties of derived
symbols to be different than their parent symbol.
CHANGED: The symbol library save menu entry is now only enable when the
currently selected library is modified.
CHANGED: The symbol library save all menu entry and tool bar button are
enabled when one or more of the symbol libraries have been modified.
REMOVED: The ability to save symbol libraries in the legacy file format.
Every time SCH_COMPONENT::GetDrawItem() was called, the schematic symbol
pin table was updated. Under certain conditions, this happens inside
loops so the amount of time spent rebuilding the pin table can add up.
