[poppler] Actual text and 0.6 branch

[Albert Astals Cid]

Hi, i've commited a patch by Adrian Johnson that adds ActualText support for 
poppler (see bug 13573)

The difference is quite appreciable so even if it's a bit "big" as patch i'd 
like to backport to 0.6 branch for the release we are having in 3 days.


As example i attach what i get with old and new code.

*** OLD ***
म नव धक र ण ज गत-अ भघ षण {अ य-भ ष -रूप न्तर ण स म यश्च}


*** NEW *** 
मानवाधिकाराणां जागत-अभिघोषणा {अन्य-भाषा-रूपान्तराणि सामग्र्यश्च}


The second is what there is on the pdf, the first seems a joke :D

Opinions?
