This commit adds:
- user.prototype.verify(verifyOptions, options, cb)
- remote method /user/:id/verify
- User.getVerifyOptions()
The remote method can be used to replay the sending of a user
identity/email verification message.
`getVerifyOptions()` can be fully customized programmatically
or partially customized using user model's `.settings.verifyOptions`
`getVerifyOptions()` is called under the hood when calling the
/user/:id/verify remote method
`getVerifyOptions()` can also be used to ease the building
of identity verifyOptions:
```js
var verifyOptions = {
type: 'email',
from: 'noreply@example.com'
template: 'verify.ejs',
redirect: '/',
generateVerificationToken: function (user, options, cb) {
cb('random-token');
}
};
user.verify(verifyOptions);
```
NOTE: the `User.login()` has been modified to return the userId when
failing due to unverified identity/email. This userId can then be used
to call the /user/:id/verify remote method.
