Extracting and showing PDF metadata (title and author)

[dinhani]

I have some PDF files where the filename are just MD5 hashes.
What I need for these files is to show the PDF title that is present in the PDF metadata instead of the filename.
So what I am doing here is extracting author and title from the metadata and showing them when available.

Personally I would prefer title to be displayed with the other tags like the Author/Owner, but I don't know if Tags are appropriate for that.

If you think this is useful, I will add some tests for PDF parsing because they are missing.

Hi @dinhani, thanks for opening this pull request! The "Author" tag is definitely appropriate here if you don't mind adding that in. Let us know when you're ready for this to go through review

@a5huynh It is ready for review.

I decided to show the document title under the filename because I think it is important to show both information, so I created a subtitle section.

The general idea is to have something reusable for extracting metadata from other file types like .docx, .epub and .mobi, for example.
