Uppercase username/No dependencies found

I unknowingly made the first letter of my username uppercase which caused me not to be able to run the basic scaffolded project. I received a few errors below in the console.

```
Dale:hello-world (HEAD) has an uppercase letter in its name; use lowercase only

Uncaught Error: No dependencies found for dale:hello-world (HEAD)
```

Which made it pretty clear that I should not use uppercase in my username, but I could not figure out how to change it.

Maybe there should be a warning when running `famous register` or it should automatically lowercase the provided username.

Ultimately I ended registering with a different email address and everything worked.
