Optional semantic versioning

[Gerhard]

The ability to turn off automatic incrementation in AppStudio for semantic versioning would be useful. The automatic incrementation when running AppUpload makes it difficult to move to a new minor version (for example, from v1.0.0 to v1.1.0) because AppStudio automatically adds a patch version (e.g. v1.1.1). To get a clean minor version number such as 1.1.0, I had to trick AppStudio by adding a negative value (see screenshot) to the previous patch number so AppStudio would arrive at 1.1.0 after a new upload.
