- added the functions for GCode View and GCode Save in Tool SolderPaste
- some work in the Gcode generation function in Tool SolderPaste
- added protection against trying to create a CNCJob from a solder_paste dispenser geometry. This one is different than the default Geometry and can be handled only by SolderPaste Tool.
