Update library adds whole library not just changes

It'll have to be later, having a bit of computer trouble now. Not related (I don't think)

I think I've fixed it now, I put the old library files back in and just to try it I ran the update command on my Pi.
This didn't take long and now when I update on my PC over the network it works as it used to/should do.
I don't know why this suddenly fixed it but it did.
In the process of copying files across I lost my original library files due to me being an idiot so I've lost all my progress and can unfortunately no longer email you a copy of the file, sorry.

Well, the thing is that it works now, I hope you'll enjoy the new features.

If the update finally worked we can live without the files

Thanks for reporting the issue.
