+oasis-net-runner: Set default max_allowances, increase test account balance
+
+The max_allowances staking setting in the default oasis-net-runner fixture has
+been changed from 0 to 16 matching the testnet and mainnet setting. This
+enables the allowance transactions locally which are required for doing
+deposits to runtimes.
+
+The initial balance of the default test account generated by the
+oasis-net-runner was increased from 100 tokens to 1 million. This makes the
+account directly suitable for deploying and running confidential smart
+contracts (e.g. on the local Cipher instance) with more realistic transaction
+fees.
