CF-engine in pure javascript

This is a pure xulrunner application. Until we get proper install
stuff done, you need to
  ln -s /usr/bin/xulrunner-stub ./jsengine

Then you can start ./jsengine

It takes command-line options
  -debug
  -infd N  input file description, defaults to 0, stdin
  -outfd N output file description, defaults to 1, stdout
  -help    produces some help text, probably not very relevant

Files
  - components/nsCommandLineHandler.js  - the main program
      so far the only source module I have needed to write
  - application.ini  - some basic info about the application
      also tells xulrunner-stub that we have a xul application here
  - extensions  - directory created by xulrunner on first invocation
  - updates and updates/0  - directories created by xulrunner
