PDFium plugin

[Jonathan Schultz]

Please excuse the silly comment about providing an executable - I see 
that you said that we'd have to build it ourselves.

So I just tried building, got most of the way without a hitch. I had to 
also use ninja build libfx_lpng.a and libfx_freetype.a to satisfy the 
dependencies in the okular Makefile. But once that was done it seems to 
work. I wasn't too sure that it was actually using pdfium, but when I 
moved the poppler generator out of the way I could see that it is 
working. Some small differences in appearance... So at least it works as 
a proof-of-concept...
