Python-poppler-qt4

* Added __len__, __getitem__ and __bool__ methods to Poppler.Document.
The __bool__ method always returns True, even if a document has 0 pages.

* Added version() function, returning the version of python-poppler-qt4
as a tuple of ints e.g. (0, 18, 3)
* Added poppler_version() function, returning the version of the Poppler-
Qt4 library (if the version could be determined on build time), as a
tuple of ints, e.g. (0, 24, 5). If on build time the version of
Poppler-Qt4 could not be determined and was not specified, an empty
tuple might be returned.
