I would probably have split this PR into two separate PRs for the two main changes here, but for the sake of time, we'll just use this single PR here. |

I have some other remarks to the ERC20 Depositor, which I will just fix in a different branch in perun-network and will then create another PR there.
Edit: I'm not really able to write my suggestions as there are some more uncertainties regarding the implementation, so I'll add my questions in this PR.

If any of these ifs should be true, which means that an error has occurred, the function will still continue to execute

* channel: Include shared Nonce object, incrementing the nonce of an account while the transaction is broadcast. Implement sync.Mutex, locking the nonce incrementals. In erc20_depositor.go, the depositing process is locked during the "Approve" function call with ```lockKey```. The function ```(d *ERC20Depositor) Deposit``` is renamed to `````(d *ERC20Depositor) DepositOnly` * client: To avoid timeouts caused by the added locking mechanism during ERC20 deposits, ```context.WithTimeout``` and ```twoPartyTestTimeout``` has been increased in fund_test.go and payment_test.go. * client/test: Timeouts have been increased to avoid premature timeout errors due to the locking mechanism above. --------- Signed-off-by: Ilja von Hoessle <[email protected]> Signed-off-by: sophia1ch <[email protected]>

This PR fixes #41 and modifies the depositing mechanism of the Ethereum backend for ERC20 assets. Both changes enable the backend to handle multiple payment channels for one Perun client.
