fix bug that appears if datatype in the project tree is renamed to wrong name (keyword, existend type,...)

This project contains wamp client config to be loaded at runtime startup.  

project_files/wampconf.json

wampconf.json is in "Project Files", so it is copied to runtime's working directory, and then loaded after program transfer + runtime restart.

Otherwise, wamp config file path can be forced :
./Beremiz_service.py -c  /path/to/my/wampconf.json /working/dir

Crossbar test router configuration is available in .crossbar directory. Start with :
crossbar -d start
