 - added some parameters throughout camlib gcode generation functions; handled some possible errors (e.g like when attempting to use an empty Custom GCode Toolchange)
 - added toggle effect for the tools in the toolbar.
 - enhanced the toggle effect for the tools in the Tools Toolbar and also for Notebook Tab selection: if the current tool is activated it will toggle the notebook side but only if the installed widget is itself. If coming from another tool, the notebook will stay visible
