Config::jfdi scans a directory for files matching a certain name. if such a file is found, and it matches an extension that config::any can read, then the configuration from that file will be loaded. it also looks for special files that end with a "_local" suffix, which take precedence over any other configuration files. the precedence takes place by merging the local config with the standard file using hash::merge::simple (libhash-merge-simple-perl).

essentially, this is an implementation of catalyst::plugin::configloader that exists outside of catalyst.
