#13 Allow logging of sql statements to STDOUT

[James A. Pattie]

By setting any of the following variables to 'STDOUT' their output will be printed to STDOUT instead of to an actual log file.

• longRunningLog
• sqlStatementLog

If logging to STDOUT, then we need to prefix the output with a string so the caller can filter the output. Defaults are:

• LONG RUNNING SQL:
• SQL:

Add longRunningPrefix and sqlStatementPrefix parameters to new() so the caller can customize these values as needed.

This feature has been implemented in v0.34.
Unit test coverage added to validate it is working as designed.
