[0.11.10] Ctrl-Left click on transport belt with item

[brachiel]

Start a new game, build and place a transport belt, take any item and control-left click on the transport belt.

The notice "Can't insert to this entity" will appear. Clicking OK, the level closes back to the main menu. Pressing ESC will just close the message.

Also, it would be nice, if clicking ok on error messages wouldn't close the level without saving (since this is the default action a user would do, not pressing ESC).

Thanks for the notice, it is now fixed for 0.11.11
