Fix <properties> tag parsing and handling

Description

The features of the <properties> tag in install.xml have been cut down in IzPack 5 in comparison to version 4.

The code was able to read properties also from environment variables or a file at compile time, but it was partly buggy and the XSD did no longer allow the attributes mentioned in the documentation.

Fix the <properties> tag and make the documentation consistent again.
