Added a --fifepath option to the WAF build script.
  * Use the '--fifepath=<path/to/fife>' option to override the default search path and directly import the FIFE Python module from <path/to/fife>.
  * Modified the parpg.main module to support the new --fifepath option and ensure that the FIFE Python module pointed to by the --fifepath option is imported, regardless of whether multiple FIFE modules are already in the default search path.
