* moving all xpdf stuff from core and part to inside generator_pdf
* adding abstract KPDFText class and KPDFTextEntity to hold either
glyph, or word or textline
- support for importing PS files as pdf like on annots branch
- synced with annots branch
- abstract text layer with search for words in different lines
- added RegularArea<NormalizedShape,Shape> template class
which inherits QValueList<NormalizedShape*> and is used
to hold regular areas of given shape (finite collections of the shape)
- loading of relevant generators via ktrader for given mimetype
- the deliverables 1 and 2 of my SoC proposition are delivered
next: 1. fix one spotted regression and 2. code ghostview backend
