Title: Minor fix for 'alphanumeric' validator message

This validator uses a pattern of `/^\w+$/` and had a message saying "Letters, numbers, spaces or underscores only please", however, the `\w` metacharacter doesn't include spaces (it's equivalent to `[a-zA-Z0-9_]`), so I amended the message to match reality.
