Merge pull request #16 from bvallelunga/devtools-cli

Added Devtools CLI Guide
Corrected the guide name and added it to sidebar.
Added `scripts` array to be injected into the footer.

The array can be included from any template, allowing a single page to
embed code or link scripts as a requirement of *that* specific template.
Rather than the footer including all scripts on all pages.
jQuery now changes the link text/attr if the user is not registered
