- added default DB_DIR
- Fixed Scandalizer due to change in codaversion -> dataversion

  We'll start with version 0.90.0 and increment the second number up to 99.
  Goal is to declare a verison 1.0.0 sometime over the summer.

  To change the version, edit both SConscript.py and Makefile.

  Fix annoyance of spurious extra prompt on exit
  Add -l, -v and --version command line options

that includes a class to read CTP style parameter files.
