Use ENTRYPOINT rather than CMD.

This changes the default way the docker image runs. The motivation is to be able to use the images created here as command line tools. e.g.

$ lein uberimage
...
Built image 123asdf131 [test/image]

docker run -it test/image --arg1 param1

Previously you would have to do this:

docker run -it test/image /usr/bin/java -jar /uberjar.jar --arg1 param1

You still have the option to not have an entrypoint, but you must explicitly define that with :entrypoint nil in the project.clj config.
