Flatpak target support

[SergeGris]

Add flatpak support in configurator

Since there is Datcord project, that supports Flatpak distribution, would be nice to add flatpak build target so that it make easer installing custom app in isolated environment.

I guess I would just have it generate a directory with all of the files necessary to build a Flatpak version of your app/publish your app to Flathub? That would be pretty simple to do. I'll implement this soon.

Thanks! if it's also possible to generate and install a flatpak version locally without having to upload it to flathub, then that would be great.

This feature has been added with the latest commit.

When compile app, there should be check that there is no spaces in author name :)
Also, when i ran flatpaked app i've got such error:

This instance is first.

App starts, but such error can lead to some security issues...

I should probably just improve input sanitation as a whole. I'll do it today.

There some errors occures on first run of flatpak app and this seems to be pretty weird. How does firefox flatpak from flathub works with this?
