Support doxygen 1.9.3

If you are using the last doxygen version (1.9.3) and add a doxyfile file to your c++ project,

it's not possible to activate the "Diagrams to generate" option, in the Basic tab. The only way to use this option is to activate a previous version of doxygen in eclipse. 

It would be necessary to update the eclox plugin to be able to activate again this option if you are using new versions of doxygen.

• [ ] add all supported configuration tags by version 1.9.3
