Version 0.2.0

Not gonna lie, the main reason this release exists is to see if the update-notifier module works.

What's new:

• An ASCII yeti/snow monster greets the user post-install, and when setting up a new project
• The installer runs npm install, bower install, and bundle separately, and shows a visual indication of which step it's on
• Apparently the watch and build commands work, although I thought they didn't.

What's left:

• Documentation related to new -v and new --libsass should be taken out, as those features won't be ready for 1.0.
• The docs command should link to the production URL of the Apps documentation.

Eventual goals:

• Integrate analytics by way of the insights module
• Add support for installing a specific version of the framework, or switching to libsass.
