Allow Google Drive files (mainly Docs and Sheets) to be embedded in the new 2.0 Docs View so we can edit these items directly in a Doc view. This is helpful because we would like a main Doc view to house all of our "Process" docs but want to use the Doc view folder hierarchy to organize them. Basically take the concept of the new Embed view and allow this inside a Doc (unfurl the Google Drive file and allow edits). Also, allow Google Drive files to be attached to documents - right now it only allows file attachments from a PC.
