Add email and password options

[jasonvarga]

This adds --email and --password options.

Using the --email option will bypass the "Create a super user?" prompt as well as the email/password/etc prompts.

If you use --email without --password, the user's password will be literally password.

This also removes the "name" prompt from the fallback windows user logic. It's nice to get rid of the hacky tinker user-updating code. Name is not really necessary. They can always update it later.

Examples

statamic new myapp [email protected] --password=test

Password will be test.

---

statamic new myapp [email protected]

Password will be password.

---

statamic new myapp --password=test

Since you don't use the email option, the password option will be ignored, and you will get all the prompts.

---

statamic new myapp

You will get all the prompts as you always did.
