Trunk demo now running on Tomcat 8.0.36

[Jacques Le Roux]

Hi,

At http://svn.apache.org/viewvc?rev=1757318&view=rev I have upgrade our embedded Tomcat to 8.0.36 (was 8.0.36) for 
https://issues.apache.org/jira/browse/OFBIZ-7348

Though I did it in a new way by only changing Gradle settings (in 2 files) and did only few tests locally, I believe it's OK. Please reports issues if 
you encounter.

Thanks

Jacques
