Subject: init: Reset brightness in F8 invert screen colours binding

Mac OS X 10.15 Catalina sometimes (but not always) causes the internal
display's brightness to change to the maximum when connected to an
external monitor after inverting screen colours. In our F8 shortcut
which inverts screen colours, reset the screen brightness to correct
this idiocy.
