Get complete listing of gas estimates for contract

[fubuloubu]

Some way to get a gas estimate for each function in a contract would be sweet, allowing you to profile the gas-intensive functions you might have but are unaware of and also see it in client programs/editors.

@vbuterin Can this be included in the ABI output? Does that make sense? I am not familiar with the requirements or uses of that format enough

[vbuterin]

Yeah, I think it would be sensible to add the gas estimate into the ABI, alongside the other fields.

@vbuterin Easier than I thought, #308

Feel free to change the string used to store it in the ABI if you so choose.
