added ability to pass a properties map to a db conversion

If the convert function has :cfg-file metadata attached, the file name it references will be used to load properties. This properties map will be passed as a single parameter to the convert function.

 To support this, facepalm now accepts --cfg-dir command line parameter to specify the directory where the properties files are located.
