* Preparation for initial Flatpack and FlatHub integration
This integrate some initial changes required for Flatpack and distribution from FlatHub.
Also added some resources that will be used for packaging on Linux.
* Address gdkchan comment
As AppVeyor took our project down and deleted it without any comments, we are switching to GitHub Releases earlier than anticipated.
This isn't the most elegant design (and I would have prefered having a release manifest in place) but this will do for now.
The concept of release channel was also defined with this change.
The new base version is now 1.1.x to avoid confusion with older system.
Standard test CI was disabled temporarly and may be chained later as a CI job after the release job.
Users are expected to redownload the emulator to be sure to be up to date.
PS: If someone from AppVeyor read this, thanks again for ruining my week-end, I will be sure to NEVER recommend you to anyone.
Best Regards, Mary.
