Merge request of text layout restructuring

[C. Boemann]

Hi

Last week I worked on the text layout, and I'm now requesting a merge of the 
branch I worked in:

text-layoutrestructure-boemann

What I've done is moving the text runaround properties from the KWFrame class 
to KoShape

Secondly I moved the runaround code from KWord to the TextShape.
However it is still the responsibility of the application to supply the 
textshape with the relevant shapes.

This was stepd 2-4 in my big 7 step master plan that I've talked to all words 
developers about.

Please take a look, and comment.

I've made basic testing and I'm rather confident that there are no regressions. 
Many unit test might be broken, and should be disabled for now.

Review mainly requested from hanzes,pierreSt ,pinaraf, sebsauer, but also 
anyone else who think they have something to contribute.

best regards
