Handbrake "portable" is NOT really portable

[pgScorpio]

Behaviour

The "portable" version of handbrake needs windowsdesktop-runtime to be installed, but, since one important use of portable software is to run the program on a computer where you don't have any installation rights, a real "portable" version should never need additional software to be installed.

Steps to reproduce this issue

1. expand HandBrake-1.6.1-x86_64-Win_GUI.zip to a USB stick
2. run HandBrake.exe on the USB stick on a computer which doesn't have windowsdesktop-runtime installed yet.
3. you will be prompted to install windowsdesktop-runtime!
4. if you don't have any installation rights on that computer the installation of windowsdesktop-runtime will fail, so Handbrake can't be run.

Expected behaviour

Tell me what should happen
The portable program should run, no mather what software is installed or not on that computer.

Actual behaviour

Any desktop app that uses .NET Core like HandBrake requires the .NET Core Desktop Runtime to be installed. This is pretty much similar to VCRedist for other applications.
