Allow passing the name of the extension if protocol object was created with get_from_file().
* Use pdftotext (program from poppler-utils) to extract text from PDF files. * Don't try to extract text from files that don't have a '.doc' extension.

Currently there is an attempt to extract text from an attachment using antiword (assuming it is a Word document).
In this change the type of the file (the extension) is considered, and antiword is only run on 'doc' documents.
The text of PDf documents is extracted using the command-line tool pdftotext (In Debian: of the package poppler-utils, generally: included the the library poppler).
I looked at several existing Python binding (Except the poppler ones, that pull a large tree of dependencies: either QT or Cairo), and those don't seem to work. pdftotext returns the full text of the page. Separating to pages later should be possible by splitting on 0xC (form-feed) characters.
