Use short arguments

[vitogit]

A conversation in this pr https://github.com/vitogit/pgn-tactics-generator/pull/20 about arguments

I am wondering if we shouldn't invert the logic (meaning) of the argument: having something like skipBlunder instead of includeBlunder. Then we could have simpler construction, like ./main.py --skipBlunder

I think we can have shorthands for the params, like -sb to skip blunder or just -s, -q for the quiet param, etc
