packaging scripts
test that run a tournament with the right number of opponent teams (issue #14)
synchronized currentVersus in VersusSequenceArena
renamed GameRunner to Player
the composition root exposes 2 players : a practice one and a versus one, so that we can work on the first and still have the second one working
added boolean battle-day parameter BattleMode that is false and that we'll have to switch to true on battle day ; the flag disables/enables the PracticeAgainstBots and Tournament tests
no need for the test arena health check anymore, and we certainly don't want it to slow us down on b-day
renamed package adapters to http.adapters
