Update for setImageValue() inside clonedBlock with indexed values

[Amerlander]

This is:

• a bug report

Expected Behavior

The cloned imagefield ${IMAGE:10cmx15cm} should return like ${IMAGE#1:10cmx15cm}

Current Behavior

Its returned like ${IMAGE:10cmx15cm#1}

Failure Information

I changed the RegularExpression in indexClonedVariables() for fixing this behaviour. It works for my purpose, but I didnt checked further:
$results[] = preg_replace('/\$\{(.*?)(:([^}])*)?\}/', '\${\\1#' . $i . '\\2}', $xmlBlock);
