Support CSV/JSON/Reddit output for "breakdowns"

[Badaro]

Currently meta, card and winrate breakdowns can only output to console. I'd like to expand this functionality to support outputting them to CSV/JSON/Reddit.

Current implementation plan:

• Only one type of output will be supported per invocation - you won't be able to output meta breakdown to JSON and card breakdown to CSV on the same call
• Should include support to specify output filenames for each type of breakdown

WIP on this branch:
https://github.com/Badaro/MTGOArchetypeParser/tree/multiple-output

• Modify IOutput interface so it includes methods for the different outputs
• Modify the code so that it always outputs to ConsoleOutput + selected output
• Move the code that computes the breakdowns from Program into a more appropriate class
• Implement new output methods for JsonOutput
• Implement new output methods for CsvOutput
• Implement new output methods for RedditOutput

Also considering just dropping RedditOutput since it's not as important and I personally don't want to support that site anymore.
