Abstract contract address from user

[Andreadinenno]

As a user of the cli, i don't want to care about contract addresses and other low level info, rather I'd like to call contract functions using the contract name.

The contract-instance object should keep track of the deployed address and internally use it.

Futhermore, user should have the ability to set the contract address associated with a name.
