Adds remove parameter to database write() function
This parameter has been added in order to obtain proper parallelization support for layman sqlite databases. With this additional parameter it prompts the sqlite db module's write function to simply return when removing an overlay, preventing it from re-adding any database entires and causing oddness, run-time errors, or other unwanted badness.
