Create settings menu

[seamustuohy]

The settings menu will allow a user to track commotion_client wide settings. These settings include sections for controlling alerts, network interface defaults, application settings, sounds, translation & usability, privacy, security, updates, and an advanced menu for controlling logging, and crash reporting.
