This initial version (called 'poppler-cpp') includes preliminary support for:
- document (loading from file name, some query methods, unlocking, font listing, embedded files)
- page (some query methods) with page transitions
- TOC

Modelled a bit on the Qt4 API, it provides also an own "ustring" typedef representing UTF-16 strings,
with methods to convert back/to UTF-8 and Latin 1.

Most probably it has bugs, but nevertheless worth testing and developing.
