description:
implement three new variables for run_rc_command:
    - ${name}_chdir     directory to cd to before running ${command}
    - ${name}_nice      nice level to run ${command} at
    - ${name}_user      user to run ${command} as

based on [misc/9954] by Dave Sainty <dave%dtsp.co.nz@localhost>, except that it works :)
