Allow copy/pasting of text from Google Docs and PDFs

Feels like an easy improvement to allow users to copy and paste text from placed Google Docs or other files. We have copywriters who post their copy using a Google Doc to a board, and the only way to extract the type without retyping the whole thing is to download it and open it. A lot of extra steps when it seems so simple to allow highlighting/copy/pasting within Miro!
