TranRed 34f820be18 implemented fallback logic for corrupted window layout (#1039)
* fallback logic for corrupted window layout

1. before saving the window-layout a backup will created to avoid corruption due to crashes while saving

2. when starting chatterino and the window-layout file returns and empty window layout (due to corruptio) the backup will be read and the layout will be build from this data

* Update WindowManager.hpp

* used QSaveFile instead of crude custom implementation

* implemented suggested feedback from review

* proper method call

was tired and slightly drunk Kapp
