ignore duplicates in history

[sdavey]

please add an option to ignore duplicates in history. I'd like to be able to use this history list as a way of switching back and forth between requests. I'm often testing several endpoints at once and need to repeat tests after making changes. If duplicate requests were not added to the history list then it would be easier to switch around between requests on a shorter history list.

I see that I should be using Collections instead of History, so I'll close this. Please disregard.
