Correct trash or trashforbidden icon and tooltip in cylinder table

Browse source 
Display the correct trash or trashforbidden icon and tooltip in the cylinder table.
This should fit together with if it is really possible to remove a cylinder.

Search for "same gas" based on used cylinders only. Otherwise one could remove
a used cylinder because there is an unused cylinder with same gas.

ToDo:
In planner update trash icon on change of planner points.
