Before all transactions were processed and when the failure was
simulated a message was printed and all the transactions still
processed. Now the store returns an error when the failure is simulated
which the listener expects so that it can gracefully shutdown the system
and close the context. The context must be closed correctly or the
checkpointer won't save the last processed transactionId to the file
system.

Created packages for the flat file store and the processor and moved
functions, variables and constants from listener.go to those packages.
Encapsulated everything not used outside the packages, introduced
model.go files which later might be extracted into a model package and
renamed parser/parsedBlock.go to parser/block.go.
