PS:
Seems like removing GH_PLUGINS_DIR had a sense because without it the options for signing & verifying don't appear twice. Didn't get that before...

> The main problem was that the folder 'tryton' in client 3.8 was renamed to 'gnuhealth' in client 4.0. Since crypto plugin did not change since 3.6 it was still trying to import from 'tryton' instead of 'gnuhealth' and the errors didn't appear in the logs.

> - In client in gnuhealth/plugins/__init__.py 'GH_PLUGINS_DIR' is not used anymore even though it is still defined in gnuhealth/config.py
> - For loading modules in gnuhealth/plugins/__init__.py exceptions should at least be printed, this was really painful to find the problem if nothing is printed after an error even in debug mode. So after 'except ImportError:' there should at least be some debug output instead of just 'continue'.
