Magento upgrades

[slackerzz]

Every update overwrites:

• packages.json
• dev/tools/grunt/configs/themes.js

Could be possible to rename them to something like packages.json.sample and themes.js.sample?

I agree.

Fortunately packages.json.sample is already available in Magento 2.1.0-rc1, see this commit: 9ba77d9

The themes.js file remains unchanged for now. Hopefully that one will get renamed too.

I've just submitted a pull request for theme.js

👍

Pinging @xcomSteveJohnson as these changes will require the documentation about npm & grunt to be updated (http://devdocs.magento.com/guides/v2.0/frontend-dev-guide/css-topics/css_debug.html#grunt_prereq).

@hostep acknowledged, thanks!
