FINERACT-2169 - New command processing infrastructure

[Viktor Pavlenko]

Hi guys! I have some suggestions about "clean up unnecessary prettyPrint
parameter from our API".
I think, that is deprecated, because many browsers and tools can easily
parse our json to prettyPrint format. And the server must not do it! Server
should only send (correct/faster) responses to the client and the client
can do everything with this json...;) So, what do you think about it ?
