While it's still work in progress, I though I'd post what I got so far here anyways.
I was getting Uploaded file is too large: current limit is 2M. To adjust this limit change 'upload_max_filesize' in php.ini. when trying to include my additions to libraries in the patch ('cause it's 28MB) so I've uploaded them separately here:https://drive.google.com/file/d/18jB1pm1ocW5pCrgZBE1lxeeAkOkPV0_q/view?usp=sharing
It's just boost asio & some json parsing library.
Oh, here is a screenie of the progress so far.
