Added support for saving and reading the options values to a file, "options.xml". This should make it easier to create a variety of settings files and try to decide which settings are the best together. It also allows for finer tweaking of the settings by editing them directly with a text editor.
This section still needs some cleanup, but works well enough for now. I will probably tweak it a little bit more tomorrow and then redistribute to those interested in trying it for me.
As the code is now becoming more complex, I am thinking that I've overlooked NUnit long enough. I will probably look at that tomorrow or in a couple of days.
