* Don't wait for any subprocess, just the one we forked.
* If the application name is not set in a cdf file, try to see
  if it has a directory with the application name on it.
* Fix ELF lseek(2) madness. Inspired by PR/134 by Jan Kaluza
* Don't use variable string formats.
* Fix detection of Zip files (Mantis #128).
* Make some minor improvements to file(1).
* Rename MIME types for filesystem objects for consistency with
  xdg-utils. Typically this means that application/x-foo becomes
  inode/foo, but some names also change slightly, e.g.
  application/x-character-device becomes inode/chardevice.
