Change client_id for Google Drive Integration

[gconsigli]

Currently, the client ID for the Google Drive integration in the PR will only work for developers. This will be an easy fix once this extension is made public on the Chrome Web Store, but we will need to change the client ID to credentials verified with the Google account the extension is published on (in the plasma config and package.json file). The new client id must have the drive read only scope added to it.

PR with Google Drive integration: #13

Assigning this to @LucaVor, who will eventually publish the extension to the Google Web Store.
