Changes in 7.0:

7.0 is a major release that contains several breaking changes, especially with Localization. If you use FluentValidation's support for localization please read the updated documentation: https://github.com/JeremySkinner/FluentValidation/wiki/f.-Localization

* Localization rewrite to not require satellite assemblies

* Fix - Ensure IValidatorFactory is resolved from request scope in asp.net core integration
* Fix - Property getter that throws an exception causes validation to fail in WebApi integration
* Fix - Issue in AspNetCore integration where we tried to resolve a collection validator in some situations where a class validator should be used
* Fix - Incorrect clientside validation attributes generated for email validator and credit card validator in the asp.net core integration
* Fix - Child model validation now works in webapi integration
* Improve splitting of PascalCased property names to support uppercase character sequences
* ValidationResult.ErrorCode property now always returns the type of the PropertyValidator that generated the message, unless it's been explicitly overriden
