Release v1.5.0

Since version 1.4.1, these changes have been made:

• Server Side Validation Validations have so far been client side. This enables them server side (useful to avoid malicious submissions that bypass JavaScript). You can disable server side validations in the ~/config/formulate/submissions.config file by setting enableServerSideValidation="false" (useful if you are using conditional fields with some potentially hidden fields being required). If you have any custom validations that implement IValidationKind, you'll need to implement the method IsValueValid, which you can see an example of here (simply return true if you don't want to worry about validating server side): https://github.com/rhythmagency/formulate/blob/303118e6f5a546a835eb979432bcf8460b2f4eb0/src/formulate.app/Validations/Kinds/Mandatory/ValidationMandatory.cs#L104
