What was wrong?

We do not yet perform overflow/underflow checks for multiplications.

How was it fixed?

Pretty straight forward based on the previous implementations for add and sub. Except for that pesty rusty-evm bug that I created an issue for: #285

@g-r-a-n-t I skipped the failing i256 test for now and created an issue. I'll try to get this fixed upstream. This is ready for review now.
