More control in the "show" panel

[liamhuber]

Let's put more data in the "show" panel (e.g. the job_table() for the project node, the hdf5 storage for jobs, etc) and control it by pushing buttons in that panel (e.g. to show and hide the structure printout when looking at a plot3d).

It would also be nice to limit the vertical size and just rely on a scroll wheel.

Source from Joerg's comment in #54 :

• The show button is really great. For nodes like BulkStructure the output gets however a bit lengthy since below the 3d-plot also the structure is printed. An idea may be to split the graphical representation (3dplot) and the text output horizontally rather than vertically. Also, the print window may be restricted in vertical size and using a (vertical) scrollbar. It may be also convenient to have something like a checkbox to show/hide a certain input. I like e.g. the solution in the plot3d node where <I can choose whether I want to show the printout. Having such a box in the corresponding output window may also be a good option.

Ok, there are check boxes for different representations and some new, richer representations of particular nodes.

Also, the print window may be restricted in vertical size and using a (vertical) scrollbar.

I'm not sure we need this anymore. Having the representation window be very long doesn't mess up anything else in the gui anymore, and if you really want to shrink it down you can now turn off lengthy representations. I'm not totally closed to this idea, but I can very much live without it for now.
