EO.workspace Integration

EO.workspace (Enterprise Open Workspace) Integration is a browser extension which allows users to grant EO.workspace installations access to:

1) the local clipboard - given through the standard `document.execCommand()` function, but such access will not require a corresponding user event like a click or keypress if explicit permission is granted using the extension.

2) local smartcards - this access is given using the Google Smartcard Connector Chrome app, using message passing (https://developer.chrome.com/extensions/messaging).
