Allows easier conversion of legacy libraries.
Note that performance will be suboptimal as it must read/write each
library once for each symbol in the library. Doing otherwise would
require modifying the PlugIn API, which probably isn't worth it for
a one-time migration.
Spooling up a full PLAYER in the background takes too long.
This also fixes bugs around how the tables are saved, although
that was just missing code rather than anything architectural.

Allow copy of a single cell demarcated by the grid cursor.
Paste of lib_table s-expressions should always start at 0,0.
Let caller or specialized sub-class do auto-sizing; don’t
do it from within the base GRID_TRICKS.
Don’t start GRID_TRICKS menu IDs at -1; wxWidgets doesn’t
like it when you get to 0.
Add column visibility menu.
(cherry picked from commit e5071ed)
Create a new dialog to edit global and project specific symbol library
tables.
Add menu entries for new symbol library table editor in schematic editor
and symbol library editor main frame menus.
Add command event handler for symbol library table editor dialog to
SCH_BASE_FRAME so it is accessible from derived frames.
Fix bug in default environment variables initialization. A test for
existing user defined environment variables was preventing any new
default environment variables added to the list from being initialized.
