The case of property names does not matter. A map where the key is case-insensitive is thus a better data structure for storing a set of property key/value pairs. Such a type was already used by FilterConfigNode. This patch cleans up the config nodes so that all of them use the new ConfigProps type. The previous typedefs inside ConfigNode and FilterConfigNode are preserved to keep old source code working without changing it. The intention is to use the result of readProperties() directly as parameter for setConfigFilter().
