Implement contributor reference for KtaneBot (Cross-Reference)

[rocket0634]

• Include a preface to updates that include the Steam ID for the bot to match to a Steam Profile

If available, provide the custom URL for the user posting the contributor update. If such a URL is not available, instead provide the profiles/<id> available from SteamUser.GetSteamID()

This should only be necessary if the contributor is not the owner of the workshop entry.

Since the modkit communicates through steam to push updates, it should be possible to get the user's ID prior to pushing a change. But this would require changing how the modkit currently functions.

The expected format of contributor updates will be Contrib. [URL]

The custom URL can be queried through Steam’s Web API but that’s probably not worth the effort. I’d prefer it to just be Contrib. [Username](URL). The username can be retrieved with SteamFriends.GetPersonaName() and the URL can just be the standard profiles/<id> URL.

@Qkrisi It is possible to get the custom URL without needing a steam key. You can query https://steamcommunity.com/profiles/<id>?xml=1 and then grab the from there. Would that make it easier?

[Qkrisi]

It would, but I think the [Username](...profiles/<id>) would still be better, since on Discord it'll show up as the acual username of the contributor, and I imagine the ID is better for Logbot to search who to ping since it's constant?
