Small class added to support csv file loading and saving.
Whole new take management. The takes are saved in a csv file named
balls.csv in directory ../ (will change in stable release). On
initializing, the file will be loaded and all takes are global
available.

TakeDialog: Now supports delete/save for single takes.

MainWindow: New input elements for the additional take parameter 'name'
and also for the parameter hardness.

Project (General): Include header path changed to the old one in order
to use just one single folder for the whole application
