Update branch to latest from pxCore #80
Description
The duktape_proof_of_concept branch needs to be brought up to date with the latest in the upstream master branch from pxscene/pxCore (https://github.com/pxscene/pxCore). Any conflicts with the latest code need to be resolved. The goal is to be able to merge the branch into master after the challenge completes, if the client requests that.
