New Windows executable that puts the SQLite database in Write Ahead Logging mode (issue https://github.com/NAVADMC/SpreadModel/issues/150). Can tell that it's working if -shm and -wal files appear in the same folder as the database file during database operations.
Gets rid of the exp__Ini output variables (issue https://github.com/NAVADMC/SpreadModel/issues/214).
Merge branch 'master' into Windows
