- added a new TclCommand named PlotObjects which will plot a list of FlatCAM objects

- made that after opening an object in FlatCAM it is not automatically plotted. If the user wants to plot it can use the TclCommands PlotAll or PlotObjects
- modified the TclCommands that open files to not plot the opened files automatically
