Improvement of the styles handling in Calligra

[Inge Wallin]

I wrote some documentation during the weekend at 
http://community.kde.org/Calligra/Code/Styles. It is mostly documentation of 
how styles are handled in Calligra today but at the end there is a suggestion 
for an improved system.

I got the thumbs up from boemann for this proposal but before I start coding 
I'd like other people to take a look and give feedback.  So please take a look 
and say what you think of the idea. It would be good if we could clean up this 
very vital part of the engine.
