Switch TradingMechanism quantities to int, add yes/no and select prompts

TradingMechanism's q/quantity params move from long/long[] to int/int[]
to match the rest of the domain (Trade.quantity, Option counts, etc.
are already int).

Add InputProcessor.readYesNo and readSelect for upcoming menu commands
that need a confirm prompt or a pick-from-list prompt.
