Improved build.sh Docker build script

 - Changed most variables from hard-coded export's, so that they only use their default value if
   the variable wasn't already set in the environment

 - Refactored most lines to follow shellscript standards, e.g. using `${}` where appropriate, quoting
   arguments and variables, etc.

 - Added some additional variables to make it easier to adjust individual portions of the docker tag
   through environment variables

 - Added basic information comment block to the top of the file explaining how to use the build script,
   and how to adjust the docker tag

 - Added a bash shebang and made the file executable

 - Added support for overriding the docker tag by passing an argument

 - Added `$DIR` variable, allowing `build.sh` to be ran from any working directory, without running
   into path context problems.

# Quick Docker build script for Jussi. Builds Jussi as a docker container.
#
# By default, the image will be tagged as 'hive/jussi:TAG' - where 'TAG' is the current
# Git branch / tag.
# If 'master' is checked out, then TAG will be changed to 'latest'.
#
# You can override the Docker image tag like so:
#
# # These will both simply tag the image as 'jussi' - no user/org, and no version tag
# # (the version tag would default to :latest)
# ./build.sh jussi
# DK_TAG_FULL=jussi ./build.sh
#
# # This will tag the image as 'someguy123/jussi:v1.2.3'
# IMAGE_USER="someguy123" IMAGE_TAG="v1.2.3" ./build.sh
#
# # This will tag the image as 'example/my-jussi:TAG' - where TAG will be
# # automatically determined from the git branch/tag.
# REPO_NAME="my-jussi" IMAGE_USER="example" ./build.sh
#
# # You can override the entire USER/REPO portion of the tag by setting IMAGE_REPO_NAME
# # This would tag the image as 'jollypirate/custom-jussi:TAG' (TAG from git branch/tag)
# IMAGE_REPO_NAME="jollypirate/custom-jussi" ./build.sh
