Removed R&D lockboxes.

As per the (yet incomplete) poll and Duntada Man's post in [this](http://baystation12.net/forums/viewtopic.php?f=5&t=9376&sid=f5565960a8071de1bcfc9c890e14ea3b&start=15) thread, the R&D console now causes all protolathe items to appear directly from the protolathe, regardless of the status of the "locked" variable.
