[Pbwebgui-development] Fixing the tree system

[Martin K. <ma...@pr...>]

Hi,

I've been busy with transforming WebGUI::Page to use nested sets. So far 
so good, I've been extending it quite a lot. It now has a lot of  
functions to getcertain nodes and subtrees and I can add pages. 
Finishing it shouldn't be to difficult and transforming 
WebGUI::Operation::Page shouldn't raise to many problem either. I think 
the thing is done somewhere tomorrow.
