 Invert the behaviour of NotBlank 
Since we have the ability to use `not` as a prefix, having rules that
start with not becomes a bit inflexible, verbose, and harder to
understand.

This commit will refactor the `NotBlank` rule by inverting its behaviour
and renaming it to `Blank`. Although this is a breaking change, users
will not feel it because "NotBlank" will still be available by using the
`not` prefix followed by the `Blank` rule.
