- Runtime: Forbid parralel push/pull for a single image/repo. Fixes #311

* Documentation: replace `ifconfig` in docs with `iproute`

* Documentation: use https repo url to clone for dev setup instructions

The dockerbuilder Dockerfile was installing one package per apt-get
install operation.

This changes it so that consecutive run apt-get install operations are
batched into a single operation.

* Build: Stabilize ADD behavior

the git clone line in the dev setup instructions does not work as is, unless the user has write access

* Client: HumanReadable ProgressBar sizes in pull

Fix Mac OS X installation instructions URL

* Builder: fixed the behavior of ADD to be (mostly) reverse-compatible, predictable and well-documented.
