Borg Gripper and Module Tweaks (#985)

Fills in some strange holes in cyborg functionality, fixing several borgs that were not quite fit at doing their jobs:

-Adds rolling pin and knife to service borgs; should allow them to cook a full range of foods. I've been getting regular nagging about this one from the community
-Adds the ability to pick up assemblies for engineering/research borgs, allowing them to construct some complex devices, notably bots and motionsensing cameras.
-Several items added to research borg: Dropper and reagent scanner, for chemistry, pen for renaming bots and writing research notes, and a plant bag for working in xenoflora
-Added altclick functionality for setting transfer rates on beakers. Essential for chemistry and cooking, since borgs can't use rightclick verbs on gripped items.
