Review request for Calligra and Pierre Stirnweiss.


Description
-------

This patch tries to fix the problems/crashes which happen in the style manager. 

To get the simple crash open the default document and click on the edit button of the None (character style)

The patch uses a different model for the style manager and temporary styles that get modified to only apply the changes once the user applies them.
The model changes the internal pointer to the temporary files once they are selected and when applied resets to the original ones.
However the styles preview in the styles manager list is updated immediately.
The patch simplifies the handling quite a bit.

I did not know that Pierre was also working on that so I publish it now so we have something we can discuss.

If you like this I would like to backport it to 2.6 as it fixes quite some grave bugs compared to what we have now.
