Docx (and other Office doc) previewer support for ActiveStorage

Converts all document formats using LibreOffice first to PDF and then to an image, using build-in pdf previwer of ActiveStorage

• needs: unoconv, a command line tool which uses libreoffice, e.g. apt install unoconv
• needs a PDF converter, because libreoffice will make a pdf from the office document, Mupdf oder Poppler are already integrated into ActiveStorage, and poppler is free to use, e.g. apt install poppler-utils

The Google Drive API supports these MIME types, but if you try to filter using them, you may find you're not getting the document types back that you expect. Especially when using setMimeTypes() with Google's JavaScript Picker.

Here are the poorly documented or completely undocumented MIME types I discovered:

If you want application/vnd.google-apps.document, also use application/vnd.google-apps.kix. Source.

If you want application/vnd.google-apps.spreadsheet, also use application/vnd.google-apps.ritz. Via a private email from a Google employee.

If you want application/vnd.google-apps.presentation, also use application/vnd.google-apps.punch. Source.
