[Emacs] Better media control keybinds and `shell-command-and-echo'

Browse Source 
`shell-command-and-echo' now takes an additional argument that will
prefix the output of its ECHO argument.
Also add documentation for the function

This commit removes keybind `SPC m P' in favor of only `SPC m p' which
toggles the state of MPD between play and pause.
