HTML5 Packaging on GNU/Linux

Just wanted to share what I am working on now. Finished the initial support for HTML5 packaging on GNU/Linux.

:wink:

Soon I try to make a PR. Let’s see if it gets accepted.

Finished and made a PR for that. People interested in can test here

https://github.com/EpicGames/UnrealEngine/pull/1788

Would be nice if GNU/Linux users can test it.
