Add the ability to see the total number of words, lines and paragraphs in the document information section

There is currently no way to see the total number of words, lines, and paragraphs across all document formats when opening the document information section in Bookworm.

Alternatives.

Add the ability to view the above information for all document formats. It will be useful for everyone, I think. Currently, there is an easy way to see the total number of words, lines, and paragraphs with the NVDA add-on, but an easier way is to open the document information directly and view the above information in all formats. @mush42 Hope you will see.

Wouldn't be that hard. I'd probably handle this after the document's text has been obtained, so we can use something like NLTK to obtain the information.

@TheQuinbox It would be nice if you could do it.
