Upgrade the treatment of Dry Run Cost + Handle dryrun_accounts
This continues the almost ready to merge #31
Original PR Description
For certain use cases, it's necessary to set the balance of the app account to some nonzero value. One example is testing inner app calls. This PR allows the users to set balances for accounts and updates the existing dryrun cost field (which is now deprecated) and adds support for the new cost fields BudgetAdded and BudgetConsumed.
