Fix app ID and move Flatpak manifest
This MR does a few changes that fixes most issues related to Flatpak:
- Change the app ID entirely to
org.gnome.Meld
- Move the Flatpak manifest to
build-aux
directory - everybody in GNOME does it - Add
.Devel
suffix, just like all the other GNOME apps - Add
git
module that builds git from source, instead of copying a file
Thanks to these fixes, GNOME Builder can now successfully build Meld from main
without running into problems.
Fixes #797 (closed)
