Branches: MAIN
CVS tags: HEAD
- generally cleaning the printout screens up

- lonprintout.pm
    - printout files have shorter unique names
    - printout files when doing multiple  students are all sequentially numbered
    - cgi ids use loncommon's get_cgi_id

- printout.pl
    - only request.role.adv users get popup status windows
    - turn on autoflush
    - only update the conversion popup if actually converting
    - use a pretty version of the image name when updating the progress window
    - use updated counting system for multiple output files
    - Updated the English on the various status outputs to read better (probably need more help still)
    - <pre> the zip output

- yeah I probably should have made some of these seperate commits

    1: #!/usr/bin/perl
    2: # CGI-script to run LaTeX, dvips, ps2ps, ps2pdf etc.
