+ support multiple system properties files with variable interpolation
  loaded at initialization
+ support of configurable JVM options (-X, etc ..).
+ rearrange aaf configuration to avoid {{}} installation variables
  and use dynamic enviroment variables.
+ miscellaneous clean up in areas touched and checkstyle.
