* Go 1.13 related fixes for js/wasm
* fix windows docker deployment issue
* new 3rdparty/UGlobalHotkey example
* fix webengine module on arch linux
* support for the prebuilt Qt wasm builds
* make use of -trimpath if available
* bump Go version in docker images to 1.12.9
* fixes for Go 1.13 + retain go module 1.12 GOPATH behavior for internal/examples
* update docker images to 5.13.0
* new docker images (windows_64_shared_512, linux_512, darwin_512)
* update examples to match the Qt 5.13 api
* bump android minSdkVersion to 21 (5.0 / lollipop)
* bump OpenSSL version for android docker deployments to 1.1.1a
* let the binding use the 513 env by default
you can use QT_VERSION=5.12.0 and/or QT_API=5.12.0 to keep the binding backward compatible with your code
just setting QT_API=5.12.0 alone should also be sufficient to keep docker deployments working
if you did install an official Qt version then just set the correct QT_VERSION and procede as usual
