Changes:
1) Now the database block has the script and properties file to fill the hsqldb with the sample entries.
I wasn't quite sure whether it should go into the hsqldb block or into the databases block. Maybe we should split it up into a general setup in the hsqldb block and leave the samples entries to the database.
2) In order to copy the files into the webapp the block's build.xml needs to know it's path. So I added a "block.dir" property.
