For some reason, the schematic symbol library link was being regenerated
every time the schematic was redrawn in SCH_SCREEN::Draw(). Remove the
re-link call from the Draw() and Plot() functions.
Add function the SCH_SCREENS to update the links in all of the schematic
sheets.
Update all schematic sheet symbol library links whenever the symbol
library list is modified or any library in the library list is modified.
That should cover all cases where the symbol library links could be
broken.
Refresh schematic window after applying library changes to update any
possible symbol changes.
Add KIWAY message to update the schematic when symbol library changes
could change the schematic. The KIWAY mail was used because the schematic
frame is not a parent of the symbol library editor so wxEvents cannot be
used.
* Remove global s_NetObjectslist.
* Separate out non-owning version of NETLIST_OBJECTS_LIST into NETLIST_OBJECTS.
* Fix double free pertaining to ~NETLIST_READER().
* Remove all file-io from CvPCB.
* Remove exe launcher cvpcb, retain only cvpcb.kiface, since cvpcb.kiface has no file i/o.
* Add void CVPCB_MAINFRAME::KiwayMailIn( KIWAY_EXPRESS& mail ) and teach it to use old
netlist loading code with a STRING_LINE_READER LINE_READER.
* Fix BEGIN_EVENT_TABLE( CVPCB_MAINFRAME, KIWAY_PLAYER )
