* Add uncaught exception handler that saves stacktraces to local crash log files
* Show a Compose crash dialog with stacktrace toggle and share action
* Register crash handler activity in a separate process with dialog theme
* Remove ACRA dependencies and configuration
* Add crash dialog strings and ignore `.hotswan/`
