For each <property> in the jnlp file, set a corresponding system property when ITW launches.

For example, if the .jnlp has the following properties:

<property name="my.property1" value="value1"/>

<property name="my.property2" value="value2"/>

The ITW java process should be launched as follows

java -Dmy.property1=value1 -Dmy.property2=value2 main.jar
