morula loads settings
#95: make changes to shared/config.py -- SettingsAccessorBase is now a subclass rather than a wrapper of configparser;
frontend settings no longer uses a QObject wrapper, but uses SettingsAccessorBase directly.
fix: remove an import statement that should've been removed
#95: implement itr_sections_with_prefix
#95, #94: load XwareAdapter from the config file
update morula for adapter loading changes.
