A *lot* of changes in this release after working on it for the whole

weekend, which I finally labeled as 2.0 (I was getting out of #s):

- Changed from HOWTO to Manual (for consistency and to be able to say
RTFM :)
- Included information from the last four months of debian-security mailing list
- Whole new sections added in the security tools chapter (PKIs, VPN) which
need much more content
- Reorganised some sections to make them easier to read
.....
more detailed info in the Changelog.

To the translation teams: I'm sorry about this :(
