Revert the Security Requistion Vendor

[mbc]

Good points about the HoS losing their belt taser and the overall lower amt of security supplies. If people think it's needed, we could definitely throw in another weapon per-loadout or something.
I'll give the HoS a roundstart taser in their backpack now.

only Security or anyone who robs security of their tokens can actually obtain these said items
[...]
you can no longer raid security for stun equipment

This was actually the main focus of these changes. Read the PR description for the full brief I typed out.

If anyone here has good suggestions for loadout changes or additions we are open to improving them.
