Deprecation: #104463 - Fluid standalone overrideArgument
See forge#104463
Description
Fluid standalone method 
        \TYPO3Fluid\
has been marked as deprecated.
Impact
Using 
        override in ViewHelpers logs a deprecation level error message in Fluid standalone v4,
and will be removed with Fluid standalone v5. The method continues to work without deprecation level
error message in Fluid standalone v2.
With Fluid standalone v2.14, 
        register no longer throws an exception if an
argument is already registered. This allows to override existing arguments transparently
without using 
        override.
Affected installations
Instances with custom ViewHelpers using 
        override are affected.
Migration
Update typo3fluid/ to at least 2.14 and use 
        register.
