Implement CoreLibs/object

[SHiLLySiT]

@lyonbeckers I had emailed Panic about Playbit awhile back to see if I could take code from the SDK, but alas, they did not give me permission (and thus some loss of functionality after ee04a9d). So unfortunately we can't just copy CoreLibs/object with minor edits into Playbit, as it would violate the TOS as per the snippet you shared.

However as @gingerbeardman pointed out, we can start from the old blog post they found on Wayback Machine.

Also note: this is low priority for me right now since I don't use the object class in any of my projects, but I'd be happy to merge any PRs that implement it! 😄

I see object says: -- loosely based on http://replayism.com/code/barebones-lua-class/

That has disappeared but is in Wayback Machine https://web.archive.org/web/20150205023439/http://replayism.com/code/barebones-lua-class/
