Created SettingsFragmentViewModel to serve as an intermediary between the UserAccountRepository (db) and the SettingsFragment. Added the Accounts section to the Settings UI with a subsection to let the user upgrade its account to LTM. Added a listener that when the 'Upgrade to LTM' button is tapped, shows a dialog explaining what is needed to be LTM and its cost.
