Integrate a simple ERC20 contract

[pepyakin]

ERC20 is a contract which is simple but still executes some amount of code. Adding such a contract to the test suite would be quite valueable.

A rough list of steps would be:

1. compile inks example ERC20, obtaining the wasm binary and ABI
2. deploy ERC20's code using put_code operation (see examples of other contracts)
3. instantiate an ERC20 contract instance. Here one might need to use ABI to pass the correct input data for the init_value.
4. call the transfer function on the contract to transfer tokens to another account,
5. check if the balances are right using the balance_of function.

Feel free to ping me if you want to take this issue, I'd gladly provide more details or help if you are stuck.

I would like give this a go, but might need some assistance in pointing in the right direction.
