Test "POC for CSRF Token" (CVE-2019-12425)

Hi All,

This "test" Jira to ask your help to review and test the work done in OFBIZ-11306. We have done all our possible, and now help is welcome. If you are experienced with penetrations tools, please use them.

You can find the branch to use in
https://github.com/JacquesLeRoux/ofbiz-framework/tree/POC-for-CSRF-Token-OFBIZ-11306
https://github.com/JacquesLeRoux/ofbiz-plugins/tree/POC-for-CSRF-Token-OFBIZ-11306.

It's ready to merge in OFBiz trunk but we will not create a PR before being rassured that we (James and I) did not miss any issues. Like links without "csrf" token, or regressions introduced by the effort.

TIA
