Previously, super + r would open an extended run menu which contained
all programs to run, ssh servers to connect to, clipboard history, open
windows, *and* the calculator. It was cumbersome to open the window,
switch the mode to calculator and then have it obscure half the screen.
It was also the mode most often used.
So, these two modes have been split, and their mappings updated:
`super + shift + spacebar` opens the old extended run menu (sans calc),
the mapping mimicking the 'extended' version of the normal run mapping.
`super (+ shift) + r` opens the calculator. Without shift it opens top
left of the screen, with shift bottom right.
