Update simulator to reflect the microbit version that is plugged in

[kimprice]

If you connect a microbit device to your computer, the simulator should reflect the version of the device (e.g. V1 or V2).

If the microbit connected is not compatible with some of the blocks in the workspace (e.g. a V1 board is connected, but there are V2 blocks in the project), an informative message should be displayed.
