When match is false the html5 validation regexp should be either inverted or not added.
Since we are in RC added a fix where this is not added, but marked a @todo so that this
can be revisited and we try to inverse the regexp instead.
[Validator] Added delimiter escaping to Validator\Constraints\Regex::getNonDelimitedPattern
[Form][Validator] Added htmlPattern option for Regex Validation.
[Validator] Fixed Validator\Constraints\Regex::getNonDelimitedPattern variable declarations
[Validator] Fixed tests for Regex htmlPattern option (instead of html_pattern)
[Validation] tweaked generation of pattern to include .* when not anchors are present. Also removed the exception and made getNonDelimitedPattern private
- remove need for defining "getTargets()" method as 95% of validators use same one
- replace abstract "Constraint::getTargets()" with one that use 95% of validators
- add additional tests for "Constraint::getTargets()" method
- remove unused "use" statement in Constraint\Valid
