Performance logging enhancements

[FermJacob]

There is a feature within MAQS that allows test authors to record the elapsed time around requests (web, ui, db... really any block of code).
That feature creates .XML files in the log folder that contain all of the timers.

This feature is envisioned as an add-on to MAQS that will process those XML files into a database.
It will then provide basic analysis of the timers in aggregate, such as average response times, ranges and standard deviation.

It is envisioned that there will be 3 major parts to this feature:

• A set of SQL scripts that set up the performance timer database
• A tool for loading the XML files into the database
• A base set of analysis reports

The hope is that we will be able to implement these components once, and use them for either Java or C# versions of MAQS.
