Gripper overhaul + New borg sprites (#1518)

Fixes #1489 
Fixes #1499 

Grippers basically torn up and remade, i went down to the root and incorporated them into cyborg click and inventory code. This should make them resistant against future bugs.
Fixes all current known gripper bugs. Grippers work properly with all the stuff they should. Minor tweaks to borg modules.

In addition, i went and raided VG, TG, paradise and bay repositories, and ported all their best sprites that were suitable for us. VG station was the most lucrative by far, about 70% of the new ones came from there.
