Description

On the [survey](https://react-redux.herokuapp.com/survey), the email address validation seems to be overly restrictive about what characters are allowed in the local part. Simultaneously, it is overly lax about the "." character.

Some examples that are syntactically invalid but pass validation:
- .@example.com
- fred.@example.com
- .fred@example.com

Some examples that are syntactically valid but fail validation:
- !@example.com
- *@example.com
- $@example.com

See [RFC 5322](https://tools.ietf.org/html/rfc5322) for full details on email address syntax.

Sorry, I don't mean to nitpick, but this seems to be intended as an exemplary app and email address validation is a common thing to want to do.
