Payable as a parameter in the ABI interface JSON

[axic]

It is planned to have a modifier for functions explicitly enabling or disabling receiving value transfer (transactions where msg.value != 0).

If that becomes implemented it would be make sense including that as a flag in the interface JSON, e.g: "payable": true

This has been renamed to payable.

We want that for 0.4.0 don't we? If yes, please add the "nextrelease" tag.

Fixed in #665.
