Try a standardised versioning scheme using KDE Apps version
This should really be up to the maintainer, if there is one. If not, I think we should default to using the bundle version. Bovo's maintainer is listed as Pelladi Gabor <firstname.lastname@example.org>, but I don't see a Phab account for Pelladi or any recent activity so I think it's safe to say that it's unmaintained. In such a circumstance, I think it's appropriate to use the bundle's own version to simplify the release process.
But this does not change the *release* process.
This patch does in that this would then get increased by the increase_repos_version.sh script and added to bugzilla by the add-bugzilla-versions/add-versions.py and when someone gets round to it by a script that runs appstream-metainfo-release-update
IMNSHO the golden rule for this kind of patch is:
- is application part of KDE Applications? ☑
- has application has "relatively significant" code changes since the last time the version was updated? ☑ (gui/version.h was updated in 2015, there's been fixes since then)
So let's go with this.
