False positive for NestingConsistencySniff when constants are used as keys

[mmunz]

I needed to use something like in a solr index.queue config to get dirrefent detail page urls depending on in which folder news are stored.

  parameter.cObject = CASE
  parameter.cObject {
      key.field = pid

      # News in storage folder 1
      {$pageUid.newsStorage1} = TEXT
      {$pageUid.newsStorage1}.value = {$pageUid.news1DetailPage}

      # News in storage folder 2
      {$pageUid.newsStorage2} = TEXT
      {$pageUid.newsStorage2}.value = {$pageUid.news2DetailPage}

      # Default news
      default = TEXT
      default.value = {$pageUid.newsDefaultDetailPage}
  }

The sniff detects those as errors:

CHECKSTYLE REPORT

SUMMARY
4 issues in total. (4 warnings)

Maybe constants/variables as keys should be excluded in that sniff.
