Add a configuration to print jdbc exceptions
By default, mcmmo tries to pretty print errors, which is fine for many
cases, however; deeper nested errors can lack information, e.g.
networking related issues, while the pretty print is less intimitating
and provides useful information to users, surpressing the trace can
prevent debugging these deeper issues, this config option serves as a
compromise between scaring users and having a means to find these deeper
issues.
