Fix: Expose Adapt variable only when Dev Tools drawer is open (fixes #78)

[swashbuck]

Fixes #78

Fix

• Exposes the Adapt variable only when the Dev Tools drawer is open
• Adds this as a new "dev tip" in the drawer
• Adjust styling in drawer to reduce vertical space and add formatting to keyboard commands
• README.md - Remove required framework version and update text about Adapt variable.
• Removed some deprecated references in js/adapt-devtools.js

Testing

1. Open the browser console
2. Type in Adapt into the console
3. Open the Dev Tools drawer
4. Type in Adapt into the console

Expected results

Adapt will only be defined when the Dev Tools drawer is open. Otherwise, you will see something like Uncaught ReferenceError: Adapt is not defined.

@swashbuck is it possible to have this variable when devtools is enabled, not just when the drawer is open? It'd be more useful to have the Adapt reference in the console and be able to interact with the course.

What about having it added when the dev tools is opened for the first time and not removing it thereafter? The trouble of having it enabled as a global variable whilst booting up Adapt would be best mitigated by adding the variable as late as possible and preferably not at all without intent.

@chris-steele This would not solve our original issue when devtools is enabled until we disable it immediately before packaging it up for release. QA would be less likely to catch any errors caused by the Adapt variable being global. In an ideal world, QA would do one final check with devtools disabled before releasing, but that rarely happens.

@oliverfoster I think this would be fine compromise.
