[Box Backup] A new preview version

[Ben Summers]

I've just uploaded a new preview version for people to try.

    http://www.fluffy.co.uk/boxbackup/bin/boxbackup-0.04PLUS1.tgz

* Added configurable "max diffing time" parameter, improved speed of 
diffing algorithm in edge cases

* Added support for old versions of OpenSSL -- experimental only (but 
appears to work fine)

* Read errors on files and directories are reported neatly

* NetBSD port fixed

You will need to make some minor changes to the configuration files for 
bbackupd, see

    http://www.fluffy.co.uk/boxbackup/004-005.html

Let me know how you get on.
