Added version 1.5.005.

Changes in version 1.5.005:
    - Fixed incorrect help text.  For CREATE COLLECTION, the optional
      IF NOT EXISTS needs to come before the collection name.  And for
      DROP COLLECTION, the optional IF EXISTS needs to come before the
      collection name.
    - Changed run_xnix and run_windows.bat files so that the current
      directory will be set to the directory these files reside in
before
      running mongoSQL.  This addresses minor pathing problems some
users
      have encountered when trying to run mongoSQL.
