Irccd: import json_util from code Change how parsing values from JSON is done, the json_util functions do not throw but return a boost::optional instead. Then, create some convenient local wrappers in server_util.cpp to throw on missing values. While here, add as much as possible const qualifier on variables that will not be modified.
