Cleanup dockerfiles

[winfried-van-loon]

Cleaning up the three Dockerfiles as discussed in #15.

I've tested the Dockerfile with all three versions like so:

docker build -t laradock/workspace:test -f Dockerfile . --no-cache --build-arg PHP_VERSION=56
docker build -t laradock/workspace:test -f Dockerfile . --no-cache --build-arg PHP_VERSION=70
docker build -t laradock/workspace:test -f Dockerfile . --no-cache --build-arg PHP_VERSION=71

Assuming that's correct, it can be merged and tagged.

Great job :) Hopefully this will get merged in and do the job!

@winfried-van-loon That's really clean, thanks.

I would love to see those changes applied to the Laradock duplicated files, it will help us avoid missing support to some tools between different versions..

Agreed! Will first merge the new Workspace version into the laradock/laradock files to close the three or four open issues, will then start merging the dockerfiles together.
