Whiteboard optimization suggestions

[EasonSpirit]

1. 双击百分比回到画布中心，且缩放回到100%，单击可输入具体的百分比
2. 增加辅助对齐线
3. 可通过ctrl多选图形
4. 可以给group命名
5. 给白板一个锁定功能，在锁定时，可以来回拖动画布，但是不同拖动其中的元素，且可以直接点击白板中链接性质的内容（可以把该功能加入拖动模式中）
6. 在其他页面嵌入白板页面时可以预览，且可点击其中的链接性质的内容（比如页面双链、block引用，url等）
7. 嵌入白板的元件时，可以直接预览该原件，而不是仅显示一段文字（embed block时）
8. 无法向已有的group中添加元件，如果选中一个元件和一个已有的group并形成新的group时，引用原group的链接会失效
9. 为什么block、page和文字的字体大小标准不一致？
10. 新增曲线工具，而不是像现在只能插入直线
