Ported over the new model to go along with the old version.

Made both the Citizen and Combine NPC use seperate models to prevent their animations from overlapping.

- Added viewmodel hands

- Added spawnmenu icons for the NPCs

- Made a seperate model for the NPC since the landing animation being different on the PM always bothered me

- Made a new physics mesh because the old one look weird

- FINALLY fixed the ragdoll arms

- Changed the category to make more sense

Initial addon creation.
