Parsing of the bodytext failed for single curly braces inside.
BodyTestParser.php: After cleaning the bodytext all nesting curly braces will be replaced by complex token. stripAndRemoveComment() renamed to trimAndRemoveCommentAndEmptyLine(). process() throws an exception in case of unmatched open curly braces. New encryptNestingDelimeter() / decryptNestingDelimeter(). Remove handling for escaped curly braces in unNest() - this should not be necessary anymore.
