fixes #298 - configure Execution globally

[dcrissman]

Execution values can now globally be set in lightblue-client.properties, but can be overridden if set directly on the request.

Seeing a lot of unrelated changes, refactorings probably. Could you make those at least in a separate commit?

@paterczm - Just in LightblueClientConfiguration, and most of that is because I had my IDE generate the toString/equals/hashCode methods to include the new fields I was adding. Looks like some unnecessary "this." were accidently removed also, but everything else is part of this change.

[paterczm]

Ok, I didn't know what happened with equals.
