Add Acra for crash reporting to Debug and Beta releases
Currently, the crash reports on google play are stripped down to the bare minimum, see the current RemoteException. It doesn't become clear which component is causing the crash and also not what the user flow was that let to the crash.
Acra is a potetially privacy friendly crashreporting system. I propose to use it with email. Each crash will result in a popup asking to send the crash per mail. a mailto: link with all data gets generated and the user can choose the email client of their choice to send a report.
We can additionally add aggregated logs that the user also sees in the log fragment to the report. We should scrub ips and other identifying data automatically before sending the report though.
