New PHP version

The PHP version has been improved a lot. It now supports the latest PHP version (4.2.x), generates UTF-8 output and the new HOWTO file says the rest:

In order to publish your photos, do this:

- Copy genpics, cat-photo.php and index.php into your image directory.
- Copy the images/ subdirectory, too.
- From a konsole, with the image directory as current directory, run ./genpics

That's it. You can view the web pages when you have uploaded all the files
to a webserver that supports php.
