update preview: print/poppler (next try)

Hi,

this is an update of print/poppler to 0.59, not to be committed
yet, but to let people test builds against old (0.57) and new (0.59)
poppler.

The main change (introduced in poppler-0.58) is an improved Object
API, which unfortunately is incompatible to the old one and thus
breaks some stuff (graphics/gdcm -- i just sent a diff for it,
print/texlive/base, sent an incomplete diff, graphics/inkscape, i
have a diff, but it's kind of "working with new poppler only).

Ciao,
Kili
