Credits/Shop: Add hooks for credit related events.

[pkillboredom]

This change adds some hooks for credit related events that are used by my addon ttt2stats. This addon records stats from my server's games to a database, which is used to populate a dashboard. I've been running these changes for a while and its about time I open a PR.

Added:

• Added hook GM:TTT2OnGiveFoundCredits(), which is triggered serverside when a player has been given credits for searching a corpse.
• Added hook GM:TTT2ReceivedKillCredits(), which is called when a player recieves credits for a kill.
• Added hook GM:TTT2ReceivedTeamAwardCredits(), which is called when a player recieves credits as a team award.
• Added hook GM:TTT2TransferedCredits(), which is called when a player has successfully transfered a credit to another player.

Changed:

• TryRerollShop calls TTT2OrderedEquipment hook.

LMK if there are any suggestions. The thing I'm iffiest on is the TryRerollShop change, maybe a new hook would be better. Thanks!

Sorry, one more commit. I couldn't understand what the remaining error was in CI so I had to go get stylua.

Yeah, it can be a little confusing what it wants, especially if TTT2 isn't the root of your project (for vscode at least)

I will review this later, but just to ask, are you aware of TTT2's events? I think you should be able to get all of this data already from the events at the round end

• Added hook GM:TTT2ReceivedKillCredits(), which is called when a player recieves credits for a kill.
• Added hook GM:TTT2ReceivedTeamAwardCredits(), which is called when a player recieves credits as a team award.
• Added hook GM:TTT2TransferedCredits(), which is called when a player has successfully transfered a credit to another player.

IMHO these names are inconsistent. It should probably be more like GM:TTT2OnGiveFoundCredits(), GM:TTT2OnReceiveKillCredits(), GM:TTT2OnReceiveTeamAwardCredits() and GM:TTT2OnTransferCredits()

Besides the suggested name change I'd also like to suggest adding more functionality to those hooks. I'm thinking of "return false to cancel the action".

So this

hook.Add("TTT2OnGiveFoundCredits", "myhook", function(ply, rag, credits)
    return false
end

would cancel that action.

But this would probably break your statistics addon, wouldn't it?

In my case I did not want to wait until round end, I wanted to update the database as soon as something had occurred.

I have changed the names.

Then this is fine with me now, as soon as you undraft it, you can rerequest a review from me. Thanks!

[TimGoll]

This somehow got lost as you never updated the review state and I never checked the code state. LGTM, thanks for contributing!
