Bee Versions Save

• Fix: Bee version failed

New command:

$ bee generate routers [-ctrlDir=/path/to/controller/directory] [-routersFile=/path/to/routers/file.go] [-routersPkg=myPackage]

We made a mistake that forget to change the module name to "github.com/beego/bee/v2", so "go get xxx" failed.

Now we fix this.

Support Beego v2.0.1
