[WWcvs] webwork2: added download_hardcopy_format_pdf permission, set to $guest.

[Sam H. v. a. <we...@ma...>]

Log Message:
-----------
added download_hardcopy_format_pdf permission, set to $guest. This
allows professors to turn off hardcopy altogether by setting all the
download_hardcopy_format_* permissions to undef. Also change the default
permisisonLevel for $guest to -5, to match the permissionLevels for the
practiceUsers in defaultClasslist.lst. (It was supposed to be -5 all 
along.)
