alt/gui swapping is now fn+f1-f4

- fn+f1: swap alt and gui on both sides
- fn+f2: swap alt and gui on the left side
- fn+f3: swap alt and gui on the right side
- fn+f4: undo swaps, returning keys to their defaults

in this setup, the default key layout is a windows-style key layout, but
the keyboard can be put into a mac-style key layout by pressing fn+f1.
the keyboard can be returned to its windows-style key layout by pressing
fn+f4.
