 - in NCC tool there is now a depth of cut parameter named 'Cut Z' which will dictate how deep the tool will enter into the PCB material
 - in NCC tool added possibility to choose between the type of tools to be used and when V-shape is used then the tool diameter is calculated from the desired depth of cut and from the V-tip parameters
 - small changes in NCC tool regarding the usage of the V-shape tool
