This new flag to the getBlock API call allows us to select
a transaction based on the usage of a certain script opcode.
This uses the new metadata index.
This adds an option to the GetTransaction Flowee API to return the fees
for a whole transaction.
Support for this is added in the Blockchain (searcher) and the
RestService components.
Notice that no fees will be returned if the BlockMetaData was not
created properly.
