1. new,api,hprose 命令增加两个参数 [-module=true] [-beego=v1.12.1] 用于生成go module项目

2. generate,migrate命令不再打印GOPATH.
3. pack命令排除。
4. run命令支持传递ldflags参数
5. fix watch file bug.ignoredFilesRegExps数组对每个文件增加$,防止目录存在tmp的情况
6. getPackagePath函数被调用时如果找不到GOPATH，则看看工程有没有go.mod 有就当做go module项目处理。
7. .travis.yml检查时排除/pkg/mod/目录
