Crashing undoes all of the settings

[LingKuja]

There's still an issue with the current version of the program, where if by any chance it crashes, it will revert all of the config to the last time it was closed safely, this means that all of the presets and markers will be cancelled from the program's memory. A fix I would suggest is that the program would periodically save everything, a bit like how SDR++ and SDR# do as well. Or otherwise a way of saving the workspace and all markers, presets and stuff manually via button or hotkey like CTRL+S.
