Building a KJAR using Decision Table Templates throws NPE

Steps to building a new KJar by defining Resource objects and adding then using KieFileSystem.write(), if a Decision Table Template resource type is added then we get a null pointer exception when the KieBuilder.buildAll() method is invoked.

Sample code that demonstrates this error can be found here: https://github.com/carlmes/decision-table-template, specifically the notes in TestDecisionTableBuild.java.

I have created a proposed fix in DecisionTableConfigurationImpl.java, by implementing the missing properties in the fromProperties and toProperties methods. Please see attached updated file that has been tested to fix the issue locally.
