semver, Stable and edge

[GameTec-live]

As mentioned by @doegox one should implement a way to ensure compatability between app and firmware. This will probably happen via semantic versioning.

• your app knows e.g. that it's implementing the protocol corresponding to the firmware releases v2.x.x
• you check the existing tags
• if latest tag is v2.x.x this is fine you can update with latest commits as usual
• if you see a tag v3.x.x this means any commit above will break your app until your app is updated and accept v3.x.x versions, so you should refrain updating fw with current version of your app

Adding a toggle between the above described behavior and the current one (just pulling the latest dev), might make sense too, as some want the latest firmware without having to wait for the next release... (stable / edge toggle somewhere in the setting)
