Fixed a bug in DictionaryObject with python 3

Dict only has a "iteritems" method in python 2, python 3.
But since this code has the same behaviour as dict, it's not necessary to remplement it, so I just killed it.
Fix https://github.com/mstamy2/PyPDF2/issues/97 by checking for NULL string, i.e., ord == 0.
Used utils.ord_()

Allow ConvertFunctionsToVirtualList to be indexed with slices and longs (python2.x)

It may seem silly to allow longs, (after all, a PDF with that many pages has other problems),
but 1L should be valid as small longs should be equivalent to ints and some APIs may return
longs.

Slices are a little more obvious -- It allows the "VirtualList" objects to behave a little
more like regular lists.
addLink: bugfix and QoL improvements

All changes in pdf.PdfFileWriter.addLink:
Added documentation to make use a bit clearer.
Fixed an issue where /P was mapped to a repr'd IndirectObject instead of
a proper indirect reference.
Added support for a border-styling parameter.
Allowed rect to be a string (as before), or a RectangleObject, or a
list, to make use more intuitive.
Bugfix for dash patterns

Fixed a bug where a border with a dash pattern (e.g. [0, 0, 1, [2, 3]])
would fail to write.
str-hacks cleanup

Found the `Str` util; replaced the version_info hack in the new addLink
functionality with the proper `Str` usage.
Minor syntax correction, replaced e.message with e
