gEDA-dev: gschem component selector modification

I don't understand why you are saying that the apply button has no effect.
Consider the following steps:

1) run gschem
2) Place a few components, but after placing the second one press the ESC
   button.
3) Now go over to the component selector window and press the apply button.
4) Move the mouse over to the main gschem window and you can keep placing
   components (the component being the same component that is currently
   selected in the component selector window).

What if the user wants to just stop placing components (by hitting the ESC
key), but wants to keep the component selection window open (so that the
place in the selection tree isn't lost)?
