Donate button for Free users of ABRP

As I use ABRP once a year only on summer holidays, I’m not needing the Premium version of ABRP, but still I want to send some money to the developers. Probably my case isn't isoltaed.

So a “Donate” button in the app would be nice to send some money and another income source for the ABRP team.

Cheers from Chile, South América,
