- added the posibility to create an object without plotting it. Also if

the project is created with plot=False then it will not be checked in
Project tab
- improved the panelize command by toggling OFF the plot for the
temporary objects. There is no need to plot the temporary objects, only
the panel is of interest
- add a few aliases for the Panelize command ('pan' and 'panel')
