Breaking: #67098 - Correct required-parameter in TextfieldViewHelper 

See forge#67098

Description 

The value comparison of the required parameter has been corrected. Prior to this change, a textfield was required as soon as it had a parameter "required" set to any value even if this value was set to FALSE, the textfield was still required.

Impact 

Textfields with required="FALSE" are not required any longer.

Affected Installations 

Every installation that uses the textfield view helper with the required attribute.

Migration 

No migration is necessary.
