Addressing problems with running code for Chapter 2 (Facebook) that involved not mapping through port 5000 for Flask and the inability to launch a web browser on the host machine if an IPython NB is running remotely. Mapped through port in Vagrantfile and added stderr output and source code comments to clarify what users should do in these circumstances.

Renaming CLIENT_ID => APP_ID in configuration and shortening code lines
Implementing pattern to guarantee that a browser window can open regardless of whether IPython Notebook is running locally or remotely by tapping into IPython.core.display.Javascript and using a different/better threading pattern for the embedded Flask web server. Updating bootstrap.sh and mtsw2e-requirements.txt to reflect the need to now run IPython Notebook from a fork of its :master since this approach requires a recently added patch to its core.
Change ownership of the mtsw2e folder to vagrant:vagrant on startup
Removing unnecessary import
Updating LinkedIn OAuth flow to use JavaScript for launching a new window to ensure the code works as expected when a remote IPython NB server is running.
Simplifying the logic of the initial OAuth flow based new knowledge of how IPython.core.display.display works.
removing unnecessary import and clarifying some language in the comments
Updating .gitignore
removing unnecessary import
Clarifying comment
Fixing bad link in docs
Updating Vagrant to enable a shared folder for more easily getting data onto the VM and updating the bootstrap so that it doesn't do duplicative work. Fixes a few more glitches in the README as well
Adding shared folder with README
Adding instructions for how to use shared folders into the Welcome notebook
Update README.md

Fixes #7 - updated README with note that refers users to bootstrap.sh in an effort to better inform them about all of the specifics involved in installing the dependencies in case they decide to try it for themselves.
Update README.md
Switch use of popup to an inline frame for OAuth landing to avoid potential issues with popup blockers or browser quirks related to popups. Add note clarifying that you should be already authenticated into Facebook in the browser you are using prior to executing the OAuth flow for a seamless experience. Possibly addresses issues mentioned in #8
