kdgantt

[Inge Wallin]

While I was helping Stuart with some library work I noticed that kdgantt, a 
library to create Gantt charts, is located in / rather than /libs/ within 
Calligra. Is there any specific reason for this? 

Shouldn't it be moved to libs/, perhaps together with kdchart which is now 
located in plugins/chartshape.

The latest version of kdchart actually contains kdgantt too so that makes even 
more sense when we update to the latest version.
