Distinguish the stable from the Beta builds.

 - [x] Drop the rev number from the stable builds packages/installer
 - [x] Maybe add the suffix in the `BeveledLabel` in the installer and `FullAppNameVer`
 - [x] The patch needs to be updated so that the 7z packages include the above 2 changes
 - [x] VSFilter installer needs to be updated also
