road building card is functional but could use smoothing. Other stuff: 1) Tooke PRIOR_STATE argument out of play_monopoly_card, 2) deleted quad_cards property and sort_cards(), 3) changed AVAILABLE_ACTIONS to AVAILABLE_TRANSITIONS, 4) reinstated reset_game_state() in views.py, 5) to accomodate for Road Building card conditions in build_road(), I changed wording of first_build to free_build.
