Increment current player at start of phase in TurnOrder.DEFAULT

[delucis]

This would close #517

Changes

1. TurnOrder.DEFAULT will now increment the current player at the start of a phase and includes a check to prevent incrementing if the phase is a game’s starting phase.

2. Adds TurnOrder.CONTINUE to provide the old default behaviour for those who need it. Is this a good name? I couldn’t think of anything clearer that would still be concise.

Breaking Changes

This change will break current behaviour for anyone:

• Using v0.33 or higher, AND
• Using phases, AND
• Using TurnOrder.DEFAULT directly or not setting a custom turn.order.first

Migration

If currently using the default turn order directly, use TurnOrder.CONTINUE instead:

import { TurnOrder } from 'boardgame.io/core'

const turn = {
- order: TurnOrder.DEFAULT,
+ order: TurnOrder.CONTINUE,
}

If currently not setting a turn order (and using phases), import TurnOrder:

+ import { TurnOrder } from 'boardgame.io/core'

const turn = {
+ order: TurnOrder.CONTINUE,
}
