Removed 'match' table from the database

I updated the frcscout.sql and empty_frcscout.sql files to create a DB from scratch,
or you can use removeMatchTable.sql to make the modifications to an existing db.

I updated the MatchRecordBean and GroupByEventBean, which I think are the only beans that used the match table.

You should now be able to add/update/delete all match records without any foreign key constraint issues.
