PR Summary

Add -UseFuzzyMatching switch to Get-Command to return commands that fuzzy match to the name in order of closest match to least. Integrate this with the suggestion framework so that on a CommandNotFound exception, suggestions are shown for likely commands the user intended. The suggestions are part of the console host and write directly to the console so don't see a way to test that. In the future, we should consider changing that to using information stream.
