Goddess bills implementation (custom NPC)

[kenedos]

What this PR Does:

• Adds a new NPC that allows players to exchange their silver for "bill" items.
• Bills can be also converted back to silver in the same NPC.
• With this, players are able to indirectly trade silver with eachother (by exchanging bills, as silver is not normally tradeable).
• In addition to this, this PR includes IES Mods to set the bill item descriptions (optional in items.conf file).
• NPC and conf file option are disabled by default.

What this PR does NOT implement:

• Trading between players

This seems familiar, didn't we already have this at some point?^^ Anyway, I wonder if you considered the option of modifying trading to add silver trading. Wouldn't that be more straight forward than going this route?

I do have a vague memory of us discussing it and you showing an implementation but for some reason I was unable to find it in Melia.

Direct silver trading is also a possibility, probably an even better one, but silver exchanging is prohibited in most systems in this game, not just trading. You're not able to send silver via mail for example, or put silver in guild storage, etc. This NPC is very 'gimmicky' and I do agree it's very niche usage. Even in Laima, I don't think anyone ever traded goddess bills or needed to trade silver directly as there's buy/sellshops and for the original game there's the marketplace (auction house).

It's up to you, if you feel this NPC is too weird to be in base Melia that's fine. I do feel it's in very similar scope to what eA normally has with custom NPCs though - stylist, warper, pvp arena, etc.

Just to chime in, might've been in the Melia "1.0" with Lua scripts.

Absolutely, I didn't mean to imply that I'm opposed to custom NPCs like this. Even if we did add direct silver trading, there could be some purpose for this functionality. Though I'd prefer if everything was moved to scripts, so it doesn't require conf and core changes. The script can set up the IES mods as well and then you'd just have to enable the script to enable it all, right?

Yea, probably^^
