Add support for launcher login via tokens and file verification

Added code to LoginActor to handle client authentication via login token
Added code to LoginActor to generate the password used by the launcher to authenticate with the API
Changed code in LoginActor to replace deprecated bcrypt functions
Changed code in Account to add the field password, token and tokenCreated
Added database migration V009 containing table changes on account, new tables launcher and filehash and a trigger/function combo to update the tokenCreated column.
