create implication game_cg -> official_art

Time to talk about some elephants in the room. The biggest counterargument in previous discussions is the presence of fan works. But Looking at how they're actually tagged, and several mentions of fan games in the forums such as topic #21273, the general conscious is that "official arts of fan works are still official arts of their own", not to mention that these fan works have fan arts of their own too.
The rest of original promotional_art are mostly the same as original official_art, bigger elephant.
1. Small copyright that doesn't have a tag. This is not difficult, just a lot of work.
2. Artist's one-shots, exhibition, doujin, merch, etc.
3. Artist's own illustration series that is beyond a one-shot. It's a bit hard to define how "official" they are, since it varies from doodle to serious production. Some of them are already "promoted" because the artist released something like a game, manga or novel. Others might have a copytag, or just character tags. With the increasing amount of them we should establish some sort of guideline, the importance is something people can agree with.
Regardless, putting these tags under official art and figuring out what does and what doesn't count as "official'' is still easier than having a dozen tags each with a slightly different definition that are identical in practice.
