VNDialog

新增了“是否允许关闭对话（allowClose）”条目，优化了关闭对话后的逻辑。现在按esc关闭对话后会执行此对话后续剩余的所有指令（如果存在）。 新增立绘缩放功能。

Added a new "Allow closing of conversation (allowClose)" entry to optimize the logic after closing a conversation. Pressing Esc to close a conversation now executes all remaining commands (if any) in the conversation. Added a new zoom feature for character portraits.
