- Updated to 2.3.STABLE2.

- Updated to 2.3.STABLE2.
- Updated source URI.
- Calamaris moved to separate package.
- Removed fix.pl - it's no longer needed.
- Error messages marked with '%lang'. English messages are installed allways
  (as fallback).
- %post script creates symlink '/usr/share/squid/errors' to one of the
  follownig directories (in this order):
  * Polish.
  * Any found, but neither Polish nor English.
  * English.
  This isn't ideal solution, but I think person using squid is clever enough
  to change symlink to match his needs ;) .
- There is no manual page for squid.
- Perl scripts in contrib directory aren't compressed.
- 'squid.conf' updated for 2.3.STABLE2 with following changes:
  * Effective group "nobody".
  * Enabled logging to /var/log/squid/{access,cache,store}.log
  * Disabled internal log-rotating.
- Some perl scripts moved from %doc to %{_libexecdir}/contrib. In source
  tarball they are in 'contrib' direcotry.
- Uses logrotate instaed of built-in rotation mechanism - built-in version
  can't compress and place old logs in different directory.
- Added patches for known bugs (from Squid home page).
- Squid effective id is "nobody.nobody".
- Cachemgr.cgi moved to separated package (caching proxy doesn't have to be a
  http server).
- Cache directories are no longer initialized from /etc/rc.d/init.d/squid
  script.
  * This isn't good idea to configure same thing (where cache dirs. are
    placed) in two files (sysconfig/squid and squid.conf).
  * This is done once.

Changed files:
    squid.spec -> 1.18
