Move atlas-cli from atlas-app-toolkit to atlas-cli repository

Move Atlas CLI

This enormous pull request doesn't actually change much. Apart from moving some files around, this is almost identical to the toolkit CLI

I moved the Atlas CLI from the toolkit to the brand-spanking-new atlas-cli repository. I had to make a few changes, but the structure of bootstrapped applications has not changed. Here's a brief summary of what has changed:

• Everything related to the bootstrap command now lives in its own package (I will include a tree structure below).
• I added a Makefile to with targets to install the binary, regenerate the template bindata, run unit tests, and run unit + integration tests.
• README changes to remove old references to the toolkit.
