* SdCard HAL refactored (#135) - Refactor SdCard HAL - introduce Lockable * Screenshot and FatFS improvements (#136) - Fix screenshots on ESP32 - Improve Screenshot service - Convert Screenshot app to class-based instead of structs - Screenshot app now automatically updates when task is finished - Enable FatFS long filename support * Re-use common log messages (#138) For consistency and binary size reduction * Toolbar spinner should get margin to the right * More TactilityC features (#139) * Rewrote Loader - Simplified Loader by removing custom threa - Created DispatcherThread - Move auto-starting apps to Boot app - Fixed Dispatcher bug where it could get stuck not processing new messages * Hide AP settings if the AP is not saved * Missing from previous commit * Replace LV_EVENT_CLICKED with LV_EVENT_SHORT_CLICKED * Refactored files app and created InputDialog (#140) - Changed Files app so that it has a View and State - Files app now allows for long-pressing on files to perform actions - Files app now has rename and delete actions - Created InputDialog app - Improved AlertDialog app layout
