Allow for a text only mode

4

When i want to show a text without image, i will use code like this: ```swift SVProgressHUD.setInfoImage(nil) SVProgressHUD.showInfo(withStatus: message) ``` and then I get a error on Swift 4. But...

希望支持修改透明度 fill-opacity

生成 iconfont 文件时，希望增加一个属性控制透明度， fill-opacity ```dart case IconNames.arrow_right_gray_s: svgXml = ''' '''; break; ```
