Differentiate the NoGAEN version from official SwissCovid

[cgrigis]

A few points have been discussed:

• [x] Rename the app to LibreCHovid
• [x] Change the applicationId
• [x] At startup, display an alert to the user, requiring the user to accept or exit:
  • If GMS are not installed on the device, display that it is an unofficial free version modified to run on devices wihout GMS.
  • If GMS are installed on the device, display that GMS are installed on the device, it is an unofficial free version modified to run on devices wihout GMS, it is suggested to use the official SwissCovid
