set enhanced-button type=button default

[ustccjw]

when use in form, button's type is "submit" (default, such as chrome).
enhanced-button is basic button in material-ui (such as datepicker use), when use datepicker in a form, you do not wish to submit form when click some tool button.

@hai-cea buttonProps should not set type="button", because you may set type="submit", as follows:
<RaisedButton type="submit" label="新建活动" />

@ustccjw What I mean is that we should pass the prop along in button props - similar to how I handled tabIndex. Yes, the type prop will get passed along thought the ...other variable, but I think it's good to be explicit about it. So in button props you'll have:

type={type}
