Google Drive Embedder

Introduced \’Embed As Drive\’ option (now default) for non-native file types (e.g. PDF, Word, Excel).
This uses Drive natively rather than sending the file via the external Google File Viewer.
It also means non-native file types can be embedded based on permissions of the logged-in Google user – does not required Anyone with the link can view.

Tidied up file structure, and brought documentation in line with the new Enterprise version of Google Drive Embedder.
