Clear symbol library list from project file after remapping.

The old symbol library list save/load code does not get called in the
schematic project file configuration code.  Use the LibNamesAndPaths
static function from the PART_LIBS object.

Bump schematic file version from 3 to 4 which represents the switch to
the library table symbol linking which is incompatible with all previous
versions.

Refresh the schematic after running remapping dialog manually.
