Import : Make the supported file types clear

[jflesch]

PNG, JPEG, PDF, etc.

(since we support everything Pillow supports, the list will be long ...)

Proof this would be useful:

When I import a folder containing many PDFs, does it create multiple documents, or one document with all PDFs "merged" ?

When I import a folder containing many PNGs, does it create multiple documents, or one document with all PNGs "merged" ?

Explicit documentation is really needed !

Regarding the documentation, I've started to work on it here : https://openpaper.work/helpdesk/kb/

We should also try make it clear that it's possible to import folders of PDF.

My current idea:

• Instead of just having an option "import", turn it into a submenu, with the following options inside:
  • "PDF"
  • "Image"
  • "Folder" (while being aware of Import: Image folder import #94)
• File selection dialog must specify explicitely the file types expected (png, jpg, pdf, folder, etc)

but I also think we need to clarify first #527.

Regarding the doc, mjourdan came up with an idea I like very much : an initial document explaining how to user Paperwork : #563

I won't make a submenu. It would make importing files slightly slower and I don't think it would really be useful
