Select presets from system tray

Hi I've added a feature to select presets from systray.

Looks:

Behaviour

Selecting any preset in systray changes selected preset immediately and vice versa.
Changing preset does not require opening main window anymore.

Additional changes

Added override in canvas.h: GCC 14.2.1 was mad about it, but decided to take care of that since there are no other warnings.
Added .vscode to .gitignore: Well... I'm working in VSCode and didn't want to include unneeded files.
Added info if program gets configured for wayland in current CMake configuration

Cheers! 😄
