This change is required after de-parameterizing the i2prouter script.  I
hardcoded the file name because the $0 variable isn't expanded (because of
single quotes). When using double-quotes (and escaping with back-slashes), the
strings weren't translated. I've decided to de-parameterize until I figure out
what the problem is.

This will allow overrides to be set without editing /usr/bin/i2prouter.

i2prouter may be replaced during upgrades. /etc/default/i2p will only be
changed by debconf (e.g. "dpkg-reconfigure i2p").

- add kFreeBSD to NBI and CPUID
- add kFreeBSD to jcpuid/jbigi build scripts
- refresh debian patches to compensate for kFreeBSD changes
- i2prouter: Detect kFreeBSD and normalize its name
- clean up osid (switching to "elif") and adding support for detecting kFreeBSD
- update postinstall.sh; I2P cannot be installed using gij so postinstall.sh
  will not be run. If/when openjdk finally comes to kFreeBSD, we'll be ready for it.

At the same time I'm making more Debian-specific changes, such as
 - not checking for Gentoo (this is obviously never going to be true :P)
 - not mentioning IzPack replacing variables (also not applicable)
 - inform about dpkg-reconfigure i2p in the event someone tries to remove or
   install an initscript with "i2prouter install|remove|uninstall"
 - remove the manual wrapper instructions

before with my 'gentoo hack'.

Refresh patch to reflect the changes to the i2prouter script
