Request: getModVersion/hasModId API

[KingColton1]

So that way we can detect mod's version or has a mod using ID to do something such as: turn off if it is on server, or inform to the user that the version is outdated and can be updated to a new version.

(posted to remind you about this)

ig one of ways to implement is to request a list of mods and their versions during handshake/login part, so server could receive this list at the beginning and later used by mods

@tracystacktrace FoxLoader already does that.

The API itself is what is missing.

Update of the API idea: public Map<String, ModInfo> getModInfos(), will reuse the ClientHello system
