Fixed Escritoire GUI

* Removed extraneous honey drop input slot
* Removed microscope from background (it belong to a button).
* Redesigned hexagonal slots and buttons to prixel precise and smooth rendering using SVG InkScape. This should become the new hex slot design. So I will port it to other Forestry GUIs
* Correctly placed tile background so it no longer overlap top of Examine button.
* Added missing Examine push button with microscope icon.
