updates for Metab4_Docker

[jwhowarth]

The following changes are proposed.

1. Fix the war file installation by prefixing the $DEPLOY_DIR path to $METABOANALYST_FILE_NAME on the wget call which eliminates the need for an explicit COPY command.
2. Update docker image from Trusty (14.04) to Xenial (16.04) for better security and add an explicit installation of the required 'sudo' package not present in the Xenial image.
3. Append missing 'xcms' R package to the Bioconductor package list installed by the Dockerfile.
4. Remove the use of p_load() in metab4script.R to avoid needlessly reinstalling the R packages on every execution of the Rscript.
5. Append the '--rm' option to the recommended 'docker run' command so that the container is always automatically removed on exit. Having to manually remove the container can be confusing to new users of docker.
