0.10.0

Main changes:

● Better (smooth) scrolling from inside the view, especially with touchpad.
● Don't try to save or restore window position under Wayland.
● When the window isn't active under Wayland, hide and show it again if the tray icon is activated.
● Don't let QTextEdit's built-in undo/redo shortcuts cause a scroll jump when there's nothing to undo/redo.
● Fixed compilation against old Qt versions.
