Add a Property Exporter step type

[crlanglois]

I currently use property loader to load calibration data from a file during test.  I populate this file using export.  The problem is that now I want to write a calibration sequence as well and there is no property exporter step to do this programatically in TestStand.  I will end up writing my own code to create this to emulate the way that Import/Export does it but it would be nice if this was supported as a TestStand step.

I also use the propertyloader to load some default values for the test.

During test the user can change these values via a GUI.

Now it would be nice to have these new values for the next start of TestStand.

So I like to save these values automatically when the user Exits the test.
