This PR adds documentation for the NPC component.

The open.mp branch for beta testing can be found here:
openmultiplayer/open.mp#916

Bugs while testing? Report them here: openmultiplayer/open.mp#1134

A test gamemode built using the wiki snippets is available here:
https://github.com/itsneufox/NPC-bare-test-omp-gamemode

The goal is for the NPCs wiki code to be fully reusable so anyone can copy and paste it on the gamemode with minimal effort

Sorry, I meant that the content of the examples sections of these two markdown files was incorrect, not that there was an error in the gamemode code.

NPC_IsSpawned should use "/checkspawned" instead of "/checkshooting".
NPC_PausePlayback should not use "/npcopennode".

Just wanted to say it's a great job already done, but I also remembered about a couple of articles which probably will need to be a bit edited too.

Namely this one:

web/frontend/docs/server/Installation.md

Line 5 in 4323fb1

If you are using the FCNPC plugin, please stop for now because this plugin does not work for open.mp currently.

and this one too:

web/frontend/docs/server/LinuxServerInstallation.md

Line 12 in 4323fb1

If you are using the FCNPC plugin, please stop for now because this plugin does not work for open.mp currently.

Since there will be some porting guide from FCNPC to native omp NPCs, these lines may probably be changed with some link on this tutorial or something similar.

I added a new message, when a conversion guide or wrapper exists, someone or i can update it again and add a link.
