Adding debug info to the CLI and the general option of the main Qt app. Also took time to: * use `EXIT_SUCCESS`/`EXIT_FAILURE` constants for main.cpp (this is what is used in `src/cli`); * fixed `m_initalized` typo; * added info on debugging mode being disabled or not; * regrouped Qt related stuff in the debug output.
