Ryan Ofsky 156f49d682 interfaces: Change getUnspentOutput return type to avoid multiprocess segfault ...

Coin serialize method segfaults if IsSpent condition is true. This caused
multiprocess code to segfault when serializing the Coin& output argument to of
the Node::getUnspentOutput method if the coin was not found. Segfault could be
triggered by double clicking and viewing transaction details in the GUI
transaction list.

Fix this by replacing Coin& output argument with optional<Coin> return value to
avoid trying to serializing spent coins.
