[0.15.2] Add a trash slot to the blueprint library

[factoriouzr]

Add a trash slot to the blueprint library to easily get rid of blueprints, books and deconstruction planners by just dropping the unwanted item over the slot.

Right now it's really easy to click on empty blueprints, books, deconstruction planner, and there is no way to get rid of this item aside from putting it in a chest and destroying it.
There is also the situation of getting rid of old blueprints and books when we get updated versions from the library from another game for eg. We want to get rid of our old books etc, but there is no easy way to do this currently. The trash slot would solve this.

Yes please!

I too end up with a bunch of empty blueprints and books.

Blueprints, blueprint books and deconstruction planners can be destroyed by clicking the trash can icon in their GUIs. Clearing a blueprint is still possible via the Shift+Right Click shortcut.

IMHO: Quite intuitive and doesn't match to this new GUI.
