Commit user edits

Added a script that goes through all the staged user edits and asks if you would like to add the change or not.  Accepted changes are made to the appropriate field in the database and unaccepted edits are thrown out.  This doesn't do anything for multiple edits to the same field though.

I made some edits to two IAs (calculator, lyrics).  The output from the script is below
