Update for setImageValue() inside clonedBlock with indexed values

Using the setImageValue() with image dimensions inside search pattern like ${IMAGE:10cmx15xm} inside a cloned block with indexed values where resulting in ${IMAGE:10cmx15cm#1}. This change in the RegularExpresion of the indexClonedVariables() is changing it to ${IMAGE#1:10cmx15cm} instead.
getVariables() will still return the whole pattern, "IMAGE#1:10cmx15cm", maybe it should also be updated to just return the raw field name "IMAGE#1".
