Mark Spanbroek 131316de08 move error conversion from TransactionResponse to Confirmable
Ensures that provider no longer needs to know about error
conversion, it now localized in contract.nim.

prevent stuck transactions by async locking nonce sequencing (+ estimate gas) (#55)
- async lock during nonce sequencing + gas estimation
- simplified cancelTransaction (still exported) such that the new transaction is populated using populateTransaction, so that all gas and fees are reset
- moved reverting contract function into its own testing helpers module, and refactored any tests to use it
- updated the test helper reverts to check EstimateGasErrors
- combine ensureNonceSequence into populateTransaction

Query past contract events (#51)
Based on ethers.js's queryFilter, allows querying of past contract events, by querying the logs for a contract's event topic.

* queryFilter to query past logs
* Allow querying of past block log events
* Can query by block number or block hash

Eric Mastro c5c9534876 Refactor based on PR comments
- `TransactionReceipt.blockHash` is optional
- Block.number is optional (in case node doesn’t return this in the event)
- Refactor confirmations waiting such that there is no polling for a receipt at the start
- Make BlockHandler and SubscriptionHandler async
- change casing of constants
- change return type checking of contract method to check for `Confirmable` instead of `?TransactionRepsonse`
- Reduce miner sleep to 10ms
- Change `wait` and `Waitable` to `confirm` and `Confirmable` to avoid conflict with chrono’s `.wait`.
- Update params on `.confirm` so that the compiler can restrict values of the `int` to `Positive` and `Natural`.
- Add `Block` and `TransactionReceipt` conversion tests to test for missing block number and block hash.
- Add tests for confirmation calculations and determining if a tx has been mined from its receipt.
- Assume that blockNumber returned from node will be null or empty string, in which case we can parse as 0 and test for that condition.

Eric Mastro a3e888128c feat: Allow contract transactions to be waited on
Allow waiting for a specified number of confirmations for contract transactions.

This change only requires an optional TransactionResponse return type to be added to the contract function. This allows the transaction hash to be passed to `.wait`.

For example, previously the `mint` method looked like this without a return value:
```
method mint(token: TestToken, holder: Address, amount: UInt256) {.base, contract.}
```
it still works without a return value, but if we want to wait for a 3 confirmations, we can now define it like this:
```
method mint(token: TestToken, holder: Address, amount: UInt256): ?TransactionResponse {.base, contract.}
```
and use like this:
```
let receipt = await token.connect(signer0)
                    .mint(accounts[1], 100.u256)
                    .wait(3) # wait for 3 confirmations
```

Eric Mastro 2f97a03fe2 feat: Can wait for transaction confirmations
Allows specified number of transaction confirmations to be awaited before a transaction is considered finalised. Polls for a transaction receipt then listens for new blocks and calculates the number of blocks between the receipt and the new block.

Notes
1. Only works with websockets currently
2. Replaced transaction not supported yet
