Feature: Default network token display (#11)

Branch adds display of default network token in balance_page.dart when account doesn't have any tokens.

List of changes:
- modified balances_list_controller.dart by updating getPageData() method with check-up of account balances if there are any tokens. If there are no tokens then default network token is added with value equal zero.
- modified a_list_block.dart by updating sort method for proper sorting because previously if the default balance was in favorites, corresponding non-favorite element would still be added to Set and overwrite favorite element.
