ROSIntegration for Unreal Engine 4.23

code: https://github.com/luigifreda/ROSIntegration  (fork)
new: now this fork has been merged into the original repo https://github.com/code-iai/ROSIntegration

I recently succeeded in porting the ROSIntegration plugin to the new version 4.23 of Unreal Engine (UE). The ROSIntegration plugin allows a cool integration between UE and ROS. The plugin was already available and tested up to UE 4.22. Unfortunately, some memory management bugs prevented the plugin from correctly working (without continuous crashes) under the new version 4.23 (where more strict checks are performed on UObject and memory management). I successfully found and fixed the bugs in the ROSIntegration plugin. Now, it correctly works without crashes.
