Revert hotkey save format

This reverts the hotkeys file format to a human readable and VCS
compatible listing by splitting individual hotkey assignments onto
separate lines instead of the single key. This unifies the hotkey format
between the application configuration and export Hotkey routines.

Both hotkey formats remain readable by the same routines.
