Fixed npc_nodropweapon 2 not dropping ammo pickups

Fixed descriptions

Combine Elites should still now drop AR2 balls as per normal after toggling npc_nodropweapon_ball on and off. Note: This affects even ones pre-config to not drop any

Also, using default tools to update so no more 3 tags, sorry

Misc. typo fixes

(Most) HL:S NPCs could drop health vials on death if they have the same spawnflag bit set high (similar to most other NPCs), so now npc_nodropweapon_hp will apply to them as well

- Added (crude) support for HL:S NPCs in Half-Life Resized Maps when used with the Half-Life SWEPs addon
- Added the FCVAR_REPLICATED flag to the CVars
- Patched npc_nodropweapon_hls being able to be set to 2

- Half-Life: Source NPCs dropping their weapon on death is now dictated by a separate CVar (npc_nodropweapon_hls)
- Tool menu is also updated accordingly

More finetuning. Sorry guys this is the kind of guy I am xD
