bubnikv e15b5f4587 Fix of https://github.com/prusa3d/Slic3r/issues/16
Crashes while switching in preview through layers with arrow keys

Also added a check box to visualize a single layer only
in the 3D path view. The check box may be toggled with a 'S' key.

Added shift+U / shift+D buttons in the 3D path view to show a single
layer only.
