Moved cyborg upgrade items out of mob code and into item code.

- Item declarations have no place in mob code. MMI and pAI code being the exception.

Removed a cyborg upgrade that made them immune to flashes
- An item that removes one of the very few weaknesses a borg has? No thanks.

Removed mob\living\silicon\robot\robot_defense.dm
- It was an empty file.

Removed uplink.dm and uplink_kits.dm from WorkInProgress
- Duplicate files: they're already in the main chunk of the code.
- They are no longer a work in progress.

Here's hoping I dont break anything with this commit...
