Added
- (Linux) Add support for Zenity and Yad filedialogs.
- (Linux) Warn user when they don't have either Yad, Zenity, or kdialog installed.
Changed
- Filter out invalid stdout from kdialog on Linux. Fixes configurations that wrongfully print other stuff to the stdout of the system while kdialog is running.
**We're not supporting the tkinter filedialog anymore on Linux. If you're having issues with it please don't report them or you'll get the `won't fix` label**
