Client update notice 2017-11-10

[loftar]

I've pushed some client changes to the public repos for purposes of forward compatibility. Currently unused, but will likely be made required after the next patch, so if you want your custom clients to keep working after that, you'll want to merge those changes sooner or later. The default client is already using the changes.

The direct object of the changes is to re-enable gemstone rendering on display signs and avatar rendering on the website.

By the way, the new code also contains a variable Config.confid, which you may choose to set to something identifying your client. It isn't used for anything meaningful, but just for information. If/once there is some uptake on it, I might publish statistics on what clients are the most used.
