Enable logging of SQL queries in database service

Sometimes it can be useful to see what queries are processed by the database service.

To enable the logging of queries a message has to be sent to the database service:

/opt/visulox/bin/cmd/msg.tcl -to database -command DEBUG-SQL -sqldebug 1 

The queries can be seen in database.log.

To disable logging set the flag to "0".

To query the state, just send the DEBUG-SQL command.
