Short description of what this PR does:

There was a fairly indirect way of copying the fat jar to the root of
the project, which I simplified, as it wasn't clear that it was being used.

The old tasks were creating a -latest jar (which is an antipattern, as that name will quickly become incorrect), and also appears to be using github as a jar distribution mechanism, which is also kind of against the grain of how the rest of the Java ecosystem works. If consumers do want a fat jar, it should probably be distributed like the other jars. BTW, I also suggest switching to Bintray for your distribution -- it's a lot easier to work with than Sonatype Nexus. I can help make that happen if you're game.

The current behavior creates a sendgrid-java-4.2.1-all.jar file in the root of the project when you run the complete build. If someone can explain what is going with the whole /repo/com/sendgrid structure, I can make that happen if it's still needed, but hopefully we can find a better way to accomplish whatever that was doing than copying jars around. :)
