Up the kbucket limit

@hoffmabc I don't think I have any major tickets on my plate, I should be getting started with the review, refactors, and questions if not tonight, during the weekend on every chance of free time I get. I've been skimming already, and I'm now familiar on how the server talks to the UI and the overall codebase, so it shouldn't take too long to grasp it.

then it's a matter of starting to write tests.

I wanted to fully understand for example how MarketApplication starts and how it's listening to ports, as I'll be needing to run multiple instances on the same machine, and I wonder how this would work with respect to the DB, I'm guessing I'll also have to hack there so that each instance keeps it's own database so my tests make sense.
