[2.x] Feature: Create account on login

[joelbutcher]

This PR allows developers to choose whether or not user create an account from the login screen without having to go to /register.

This PR was inspired by #49, a great feature suggestion from @luiyongsheng. I was originally going to merge the branch in, but was conscious of adding another config item for developers to worry about. This PR resolves that worry by following the "features" pattern found in Laravel Jetstream and Fortify, becoming instantly familiar.

To enable the features simply add the following to your socialstream.php config file:

'features' => [
    \JoelButcher\Socialstream\Features::createAccountOnFirstLogin(),
]

So just to confirm when users Signin AND Create an account in the same call then they loose the following settings from their profile:

• Two Factor Authentication
• Browser Sessions
• Delete Account

I do not see these settings. It makes sense for the 2FA not being there but why were Browser Sessions and Delete Account removed?

Users need to setup password first in order to access those settings.

This is the correct functionality regardless of sign in. When you register via a provider, you don't have a password - the actions you've mentioned require a password confirmations. So setting a password will reveal these actions.
