VControl EVO Update

We prepared a update for the VControl EVO Radios. It adresses some problems that have showed up with the last version. Main Changes are:

- Optimized Sound/Vibration for the new Speaker

- Improved USB Compatibility for Simulator and USB Drive

- More reliable handling with WiFi, USB and idle mode

- Ui improvements and error corrections

We recommend doing the update so you dont run into problems that are already solved. The Update includes a new firmware, so the radio will reboot after the update. The Version of the new Firmware is 2.1.115
