restored layout of pom.xml for minimal changes in PR
Snapshot - I think I have the basic framework in place. No tests are passing and nothing works, but most of the calls and the builder are in place.

GOSSIP-65 Implement crdt LWW-Element-Set
LWWSet implemented + se/de + unit tests + jackson tests + DataTests
GOSSIP-55 Added event handlers to notify share data and per node data changes
Reformat code to match apache standard
Fixed DataTest errors WRT PNCounter
Part of what makes this work is the test implementation of TransportManager.
This PR is pretty straightforward. A few gotchas though:
* A message signing test was moved into `JacksonTests` because that is
where the signing actually happens.
* A CRDT serializing test was moved there as well. It's the best place
for now.
* No UDP tests at all. I plan to fix that in a bit. Reasoning is that it is
difficult to test any TransportManager implementation without bring up
a full stack. I plan to address this in the future (GOSSIP-83).
* Simple round trip Jackson serialization tests.
* add *.ipr to .gitignore
* modify existing pom to be a parent. create new pom for gossip-core.
* I left all properties and dependencies in the parent, as they seemed to be a fairly general set of dependencies.
move all the code.
* rename parent module: gossip -> gossip-parent
* move dependencies into child module
