- Added two fields for strategy.exit and strategy.entry functions
1) comment (string) An optional parameter. Additional notes on the order. Replaces the {{strategy.order.comment}} placeholder when it is used in the "Create Alert" dialog box's "Message" field.
2) alert_message (string) An optional parameter which replaces the {{strategy.order.alert_message}} placeholder when it is used in the "Create Alert" dialog box's "Message" field.
Both placeholders in alerts to make the strategy compatible with automated trading bots (3commas, ProfitView, Gunbot, etc.)
