ANN: 2 new Trace API / FBTM screencasts: Parametrized query detection and enhanced error tracing

Two new Trace API / FB TraceManager screencasts have been made available:

The first is discussing the usage of the Trace API to detect
parametrized query reusage, which allows to check if you are re-using prepared statements in e.g. batch processing scenarios or not.

The second demo discusses the new error/warning tracing capabilities to
be expected in Firebird 2.5.2(http://tracker.firebirdsql.org/browse/CORE-3539) and its integration/usage in FB TraceManager.
