mermaidjs渲染gantt图不支持axisFormat关键字

[XeonForce]

OS Version : Windows
VNote Version: 2.4

Symptoms (表现):

mermaidjs渲染的甘特图，vnote默认是以周为单位显示横坐标
代码中带上axisFormat关键字以修改坐标轴时，vnote无法渲染，直接显示原代码

mermaid已支持该关键字，相关issue

How to Repro (如何复现):

测试代码

gantt
    dateFormat  YYYY-MM-DD
    axisFormat  %m/%d/%Y
    title Adding GANTT diagram functionality to mermaid

    section A section
    Completed task            :done,    des1, 2014-01-06,2014-01-08
    Active task               :active,  des2, 2014-01-09, 3d
    Future task               :         des3, after des2, 5d
    Future task2               :         des4, after des3, 5d

移除axisFormat后显示正常

Should be fixed after updating the version of Mermaid.
