Update to latest yampl version, remove patch (no longer needed)
Hi,
This updates yampl to the latest version and removes the patch, which was needed for Ubuntu building. However, Ubuntu compilation appears to be fixed by https://github.com/vitillo/yampl/pull/6: @tsulaia can confirm.
The patching mechanism is somewhat unstable under CMake version changes (see ATLINFR-2651) which is why this came up.
Cheers,
Stewart
